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.

Заглавие : Nonlinear photonic crystals of strontium tetraborate
Место публикации : Photonic Crystals: Fabrication, Band Struct. and Appl. - New York: Nova Science Publishers, 2011. - P.245-275. - ISBN 978-161668953-7
Аннотация: Structural, optical and nonlinear optical properties of strontium tetraborate (SBO) single crystals are summarized. SBO presently is not considered to be a ferroelectric, however, domain structures consisting of alternating oppositely poled domains, strongly resembling those present in such ferroelectrics as potassium titanyl phosphate and lithium niobate, were recently discovered in this crystal. Such geometrical properties as orientation, size, and degree of randomization, of these domain structures are described. The problem of origin of domain structures in SBO is considered, as well as the possibility of their characteristics control. From the point of view of optical properties, domain-structured samples of strontium tetraborate are classified as randomized nonlinear photonic crystals. Comparative study of nonlinear diffraction and random quasi-phase-matching of nanosecond and femtosecond laser pulses in these nonlinear photonic crystals is presented. Prospects of creation of nonlinear optical converters of laser radiation into VUV spectral region based on domain structured strontium tetraborate are discussed.

Аннотация: We examine the spatial evolution of lightwaves in a nonlinear photonic crystal with a quadratic nonlinearity, when a second harmonic and a sum-frequency generation are simultaneously quasi-phase-matched. We find the conditions for a transition to Hamiltonian chaos for different amplitudes of lightwaves at the crystal boundary. (C) 2002 MAIK "Nauka/ Interperiodica".
