Cherenkov second harmonic generation of femtosecond laser pulses in a homogeneous nonlinear crystal / A. M. Vyunishev, A. S. Chirkin // Laser Phys. - 2024. - Vol. 34, Is. 8. - Ст. 085402, DOI 10.1088/1555-6611/ad5156. - Cited References: 37 . - ISSN 1054-660X. - ISSN 1555-6611

second harmonic generation -- nonlinear diffraction -- nonlinear Cherenkov radiation -- femtosecond laser pulses
Аннотация: In experiments on second harmonic (SH) generation (SHG), a conical structure of radiation has been observed. In the present study, a non-stationary theory of SH excitation of ultrashort laser pulses with phase modulation has been developed, which explains the properties of such a structure as Cherenkov radiation. Under phase-mismatched interactions, a maximum of the SH spectrum is observed at the Cherenkov angle, which is determined by the ratio of the SH and laser radiation phase velocities. It is shown that tightly focused laser beams are preferred to observe Cherenkov SHG. The SH spectral width depends on the group velocity mismatch and is more complicated on the excited radiation spectrum. The SH energy can be proportional to the crystal length or group delay length depending on their ratio. We also demonstrate that a complex angular distribution of spectral components (an angular chirp) appears within the SH cross-section.

Phase transitions and nonlinear optical property modifications in BaGa4Se7 / L. Isaenko, L. Dong, S. V. Melnikova [et al.] // Inorg.

Аннотация: Phase transitions can change the crystal structure and modify the physical properties of crystals. In this work, we investigate the phase transition behavior in BaGa4Se7, an important middle infrared (mid-IR) nonlinear optical (NLO) crystal, in the temperature range from room temperature to 1173 K. Interestingly, the BaGa4Se7 crystal undergoes a reversible ferroelastic phase transition at T = 528 K, resulting in the presence of a newly discovered phase (γ-phase) at the higher temperature. The experimental temperature dependence of optical birefringence, as well as the first-principles birefringence and NLO coefficients, reveals that the γ-phase exhibits larger birefringence and better NLO properties compared with those of the low-temperature phase (α-phase). This work demonstrates that phase-transition-induced structural modification can improve the mid-IR NLO properties, which would provide an effective avenue to obtain materials with good optoelectronic performance.

second harmonic generation -- nonlinear photonic crystals -- femtosecond laser pulses -- nonlinear diffraction
Аннотация: Quasi-phase matched nonlinear frequency conversion in three dimensional nonlinear photonic crystals (NPCs) has been considered for implementation of the second harmonic generation of transform-limited and chirped femtosecond laser pulses. Spatial distribution of the second harmonic intensity is shown to be caused by Cherenkov- and Raman–Nath-type nonlinear diffraction. These types of nonlinear diffraction may occur simultaneously resulting in an efficient multi-order nonlinear diffraction in the Bragg regime, which can be realized by a proper choice of the modulation period of NPC structure in longitudinal direction for considered transverse diffraction order. Three dimensional NPCs open up new possibilities for ultrafast nonlinear photonics and parametric interactions in optics.

photonic topological insulator -- cellular automata -- Wolfram codes -- Zhegalkin operator
Аннотация: A topological insulator is a material that exhibits the properties of a conductor on the surface and of an insulator in the bulk. The Rudner game is a simplified model of a topological insulator implemented on a two-dimensional photonic lattice of resonators, which is described in the language of tricolor four-cycle two-dimensional Wolfram cellular automata. It is a case of a regular two-dimensional lattice, in which each cell is colored in one of three colors (for a photonic topological insulator, these colors mean the presence of a photon in a resonator, the absence of a photon, and a topological insulator boundary). By setting the transformation rule for each cell, depending on the state of the nearest neighbors and the cell itself, for equal discrete time intervals we obtain a cellular automaton. In this study, the Rudner game is rewritten equivalently in terms of operators in the Zhegalkin polynomial ring with coefficients in a field consisting of three elements.

metal–organic frameworks -- multicolor emission -- second harmonic generation -- single crystals -- third harmonic generation
Аннотация: Abstract Non-centrosymmetric metal–organic frameworks (MOFs) have recently emerged as a promising class of coordination polymers for nonlinear optics and light conversion. Nevertheless, achieving high endurance and efficiency for the light conversion within the whole visible range by a single crystal of MOF remains a challenge. This article reports on the design of two non-centrosymmetric MOFs based on a 1,3,5-benzenetricarboxylic acid ligand and Er/Co ions, providing an efficient and simultaneous multiple second and third optical harmonic generations (SHG, THG) from 400 to 750 nm with a high endurance (over 100 cycles or 3 h of continuous operation). Optical experiments and quantum chemical modeling of the MOF single crystals confirm the polarization and chemistry-dependent efficiency of SHG and THG, associated with the varied MOFs' symmetry and dipole moment. The observed coherent light conversion within the whole visible range by MOF single crystals at ambient conditions makes it possible to achieve the multicolor (up to three) coherent emission required for modern laser technologies, making MOFs highly competitive and sustainable materials for nonlinear optics.

   Перевод заглавия: Эволюция структур и оптических свойств в серии инфракрасных нелинейно-оптических кристаллов LixAg1–xInSe2 (0 ≤ x ≤ 1)
Аннотация: In this work, a number of new infrared nonlinear optical (NLO) crystals of LixAg1–xInSe2, in which the ratio x of Li/Ag varies in a wide range from 0 to 1, are investigated. Structural analysis reveals that the space group of LixAg1–xInSe2 evolved from I4̅2d in AgInSe2 to Pna21 in LiInSe2 as x increases from low values (0, 0.2, 0.37) to large values (0.55, 0.78, 0.81, 1). Compared to other Li/Ag coexisting chalcogenides such as LixAg1–xGaS2 and LixAg1–xGaSe2, the structural distortions in LixAg1–xInSe2 are much more prominent. This may explain the limited crystallization region in the phase graph of the tetragonal structure LixAg1–xInSe2. The fundamental optical absorption edges in these LixAg1–xInSe2 compounds are determined from the direct electronic transitions and the band gaps Eg gradually increase as the lithium content increases, consistent with the first-principles calculations. The composition x = 0.78 is calculated to have a good set of optical properties with a large NLO coefficient (dpowder = 28.8 pm/V) and moderate birefringence (Δn ∼ 0.04). Accordingly, the Li0.78Ag0.22InSe2 crystal is grown by the modified Bridgman–Stockbarger method, and it exhibits a wide transparency range from 0.546 to 14.3 μm at the 2% transmittance level.

Аннотация: Optical bistability and symmetry breaking under the conditions of plane wave incidence on a system of coupled photonic crystal microcavities containing an inclusion with Kerr susceptibility have been studied. The T-matrix modal method has been generalized for the case of nonlinear microcavities supporting one monopole mode. It has been shown that both phenomena considerably depend not only on external field strength but also on angle of incidence and photonic crystal size.

chalcogenides -- energy band gap -- mid-IR nonlinear optical crystals -- second harmonic generation -- structure analysis
Аннотация: AgGaSe2 and LiGaSe2 are two famous mid-infrared nonlinear optical (NLO) materials with similar chemical formula but different structural symmetry. The former material has relatively larger NLO effect and birefringence but rather small energy band gap, while the latter is the opposite. Aiming at achieving a good balance of NLO properties, here the substitution between silver and lithium ions on the evolution of structural and optical properties in a new series of LixAg1–xGaSe2 crystals is systematically investigated. It reveals that, with the increase of Li content, LixAg1–xGaSe2 almost keeps the same tetragonal symmetry with AgGaSe2 until x ≈ 0.9. The NLO effects and birefringence values vary with respect to x with the largest variation at x = 0.8–0.9. The optimal combination of birefringence (0.03–0.025) and nonlinear parameters (26–30 pm V−1) is achieved at x = 0.4–0.5. As the energy band gap increases with the increase of x, the maximal value of 2.2 eV for chalcopyrite structure suggests that the laser-induced damage threshold of LixAg1–xGaSe2 would be as large as five-fold of AgGaSe2. This study provides a good example to show that the rational substitution between Li and Ag can significantly improve the balance of NLO properties in chalcogenides.

Аннотация: We have explored the dynamic response of in-plane magnetized thin permalloy films excited by microwave fields of high amplitudes (up to 3 Oe) at 1 GHz. The response was detected using a microstrip line by measuring the second harmonic signal generated by the dynamic components of the uniform magnetization. The data measured at ferromagnetic resonance showed the threshold effect of the Suhl parametric instability process. With the increase of the microwave power above the threshold value, the dynamic response revealed an intricate nonlinear behavior, including the emergence of an additional threshold. This second threshold can be explained in terms of the "stage by stage"process of parametric spin wave excitation following the S theory of Zakharov, L'vov, and Starobinets.

Borate -- Crystal structure -- Raman -- Photoluminescence
Аннотация: New noncentrosymmetric alkali rare-earth double borate Rb3SmB6O12 was found in the ternary system Rb2O–Sm2O3–B2O3. The Rb3SmB6O12 powder was prepared by the solid state reaction method at 750 °C for 40 h and the crystal structure was obtained by the Rietveld method. Rb3SmB6O12 crystallized in space group R32 with unit cell parameters a = 13.4874 (3) and c = 30.9398 (6) Å, V = 4874.2 (2) Å3, Z = 15. In the three-dimensional framework structure of Rb3SmB6O12, each [B5O10]5− group is linked to four different Sm-O polyhedra and, likewise, each Sm-O polyhedron is connected to four neighboring [B5O10]5− groups. The Sm-O polyhedra are formed by the face-sharing linked SmO6 octahedra. Rb+ cations are located in large cavities of the framework structure. From the thermal stability measurements, the incongruent melting of Rb3SmB6O12 is observed at 1104 K with as high melting enthalpy as Hm = –161.5 J/g. The nonlinear optical response of Rb3SmB6O12 tested via SHG is estimated to be similar to that of K3YB6O12. The Raman spectrum of Rb3SmB6O12 is mainly governed by the vibrations of BO4 and BO3 borate groups observed over the wavenumber range of 287–1550 cm–1. The spectral bands below 270 cm–1 were attributed to rotational, translational and mixed vibrations of Rb3SmB6O12 structural units. The luminescence spectrum of Sm3+ ions in the specific local environment of the Rb3SmB6O12 crystal lattice shows the ability to control the individual band intensity ratio originating from 4G5/2 level.

Double nitrates -- Crystal growth -- Electronic structure -- Nonlinear optical materials -- X-ray photoelectron spectroscopy
Аннотация: Rb2Na(NO3)3 crystals demonstrate nonlinear optical properties and can be used as a converter of laser radiation in the shortwave region. The crystals were grown in the present work by the Bridgman–Stockbarger method in a ratio of 75 wt%(RbNO3) and 25 wt%(NaNO3). After the growth, a transparent centimeter size single crystal (6 cm long) was obtained for the first time that is very important for its practical application. The unit cell volume of double Rb2Na(NO3)3 nitrate is intermediate between the cell volumes of simple rubidium and sodium nitrates, RbNO3 and NaNO3. Electronic structure of Rb2Na(NO3)3 was studied in the present work from both experimental and theoretical viewpoints. In particular, employing X-ray photoelectron spectroscopy, we have measured binding energies of core electrons and energy distribution of the electronic states within the valence band region of the Rb2Na(NO3)3 crystal and established rather big binding energies for N 1s and O 1s core-level electrons. The bombardment of middle-energy Ar+ ions induces transformation of some nitrogen atoms of the analyzing topmost layers of the Rb2Na(NO3)3 crystal surface from the NO3– group to the NO2– group. To explore in detail the filling of the valence band of Rb2Na(NO3)3 by electronic states associated with constituting atoms, we use first-principles calculations within a density functional theory (DFT) framework. The DFT calculations reveal that O 2p states are the principal contributors to the valence band bringing the main input in its upper portion. The theoretical finding is supported experimentally by fitting the X-ray photoelectron valence band spectrum and the X-ray emission O Kα band on the total energy scale. The conduction band bottom of Rb2Na(NO3)3 is composed by unoccupied O 2p and N 2p states in almost equal proportion.

   Перевод заглавия: Новый нелинейно-оптический кристалл селенида AgLiGa2Se4 с хорошими комплексными характеристиками в средней инфракрасной области
Кл.слова (ненормированные):
crystal growth -- first principles calculations -- inorganic functional materials -- laser damage threshold -- second harmonic generation
Аннотация: Mid‐infrared (mid‐IR) nonlinear optical (NLO) crystals are indispensable for the mid‐IR lasers generation with tunable wavelengths from 3 to 20 µm. AgGaSe2 is a commercial mid‐IR NLO crystal with the highest figures of merit, but suffers low laser damage threshold (LDT). To achieve the balance of optical transmission, NLO effect, and LDT, it is proposed to molecularly modify the AgGaSe2 structure by introducing the [LiSe4] tetrahedra, and successfully grow large crystals of a new selenide AgLiGa2Se4. The replacement of half of the heavy Ag+ cations with light Li+ increases the band gap to 2.2 eV (vs. 1.7 eV in AgGaSe2). The LDT value in AgLiGa2Se4 increases five times compared to that in AgGaSe2, while keeping a relatively large NLO susceptibility of 26 pm V−1. Moreover, the thermal expansion coefficients in AgLiGa2Se4 are approximately two times lower in absolute value compared with AgGaSe2, which is beneficial to the large crystal growth. All these advantages would make AgLiGa2Se4 a new promising NLO crystal for mid‐IR laser applications.

microstrip resonator -- thin magnetic film -- frequency multiplication -- nonlinear magnetization oscillations
Аннотация: The characteristics of a frequency doubler on a resonant microstrip structure with a thin magnetic film were studied theoretically. The electrodynamic calculation of the structure was performed within the quasi-static approximation. Nonlinear response of film magnetization was calculated taking into account the second-order terms in the Landau-Lifshitz equation. The frequency response of the microstrip resonator was calculated. It was shown that due to the use of the resonant circuit, high efficiency of the input signal energy conversion into the output signal at a doubled frequency was achieved. The optimal values of the magnitude and direction of an external static magnetic field, which ensure the maximum output power at a doubled frequency, were determined.

Аннотация: Second harmonic generation versus strength and direction of the applied static magnetic field was measured for a thin permalloy (Ni80Fe20) film in a microstrip line at a driving frequency of 1 GHz and maximum input power of ~110 mW. The measurements revealed two peaks in the double frequency signal—in the low static field (~10 Oe) and the high one (~45 Oe). To explain these findings, a macrospin model of a thin magnetic film with in-plane uniaxial magnetic anisotropy was considered. A perturbation expansion of the Landau–Lifshitz–Gilbert equation provided an explanation of the experimental data. The analysis of the model revealed that the low-field peak was caused by the longitudinal second-order magnetization component and the high-field peak by the transversal one. It was also shown that the uniaxial magnetic anisotropy of the film and the dependence of the magnetic damping parameter on the applied field play an important role in the process of the second harmonic generation. The results obtained give insights into some peculiarities of the nonlinear magnetization dynamics that are important in the development of magnetic film-based devices in the field of microwave signal processing and manipulation.

Crossover pressure -- High-spin ground state -- Magnetic insulator -- Metal-oxygen bonds -- Nonlinear oscillation -- Occupation numbers -- Temperature values -- Ultra-fast dynamics -- Spin fluctuations
Аннотация: Within the multielectron model of magnetic insulator with two different spin terms at each cation and spin crossover under high pressure we have studied dynamics of a sudden excited non equilibrium spin state. We obtain the different relaxation of the magnetization, high spin/low spin occupation numbers, and the metal-oxygen bond length for different values of the external pressure. For each pressure-temperature values stationary state agrees to the mean field phase diagrams. We found the long living oscillations of magnetization for the high spin ground state at small pressure. Close to crossover pressure the smooth relaxation is accompanied with a set of sharp strongly non linear oscillations of magnetization and HS/LS occupation numbers that are accompanied by the Franck–Condon resonances.
