Заглавие : Nonlinear optical characterization of spontaneously grown domain structures in SBO crystals

Аннотация: Spontaneously grown partially ordered domain structures in SBO crystals are characterized via nonlinear diffraction. Domains have the form of sheets lying in cb plane with the domain walls oriented perpendicularly to the a crystallographic axis. The thickness of domains varies in quite wide range. The effective thickness of domains contributing to the nonlinear diffraction is determined from Fourier spectrum of inverse superlattice wave vectors to lie between 180 nm and 8 microns. General properties of spatial Fourier spectrum are reproducible from one growth procedure to another, however, details of spectrum noticeably vary. Enhancement factors for random QPM are calculated and found to be of order of several thousand in the near UV.

Аннотация: Random quasi-phase-matching (RQPM) of the second-harmonic generation process is investigated experimentally and theoretically in a strongly randomized spontaneously grown nonlinear photonic crystal structure of strontium tetraborate. The thickness of domains in the structure is measured and employed in calculations of angular and spectral dependences of random quasi-phase-matching. Despite the great scale of randomness, the RQPM effect is preserved. The calculated enhancement factor due to RQPM is in excellent agreement with experiment, and good agreement between calculations and experiment is obtained for the shape of the angular dependence of RQPM. The calculated spectral dependence of RQPM consists of a number of narrow peaks, and a maximum enhancement factor is attained in the near ultraviolet. The band structure of randomized nonlinear photonic crystal is calculated.

Аннотация: Random quasi-phase-matched frequency doubling of fs pulses to the deep UV was obtained in 1D nonlinear photonic crystal (NPC) of strontium tetraborate. Tuning range of generated radiation is from 187.5 to 215 nm. The spectrum of generated radiation consists from series of peaks with the width of order of 1 A. These peaks are the manifestation of the NPC band structure. Using fs oscillator as the fundamental radiation source, maximum average power of generated radiation is of order 1 ?W, the enhancement factor with respect to monodomain sample being of order of several hundred. The red rotational shift of NPC band structure is experimentally demonstrated. © 2011 SPIE.

Ключевые слова (''Своб.индексиров.''): nonlinear photonic crystal--strontium tetraborate--second harmonic generation--random quasi phase matching--ultrafast diagnostics
Аннотация: The properties of NPC structures in strontium tetraborate are analyzed. Different types of NPC structures are revealed that possess different nonlinear properties, and their spectral dependences of frequency conversion efficiency are calculated and compared. Experimental study of these structures is reported for the process of doubling of the second harmonic of fs Ti:S laser. Tuning of generated radiation is obtained in the range 187.5 - 232.5 nm, with extreme insensitivity to the angular orientation of NPC. Behavior of tuning curve along investigated fundamental wave range is similar in all studied samples, but efficiency obtained depends on the type of structure. Conversion efficiency and spectral quality of generated radiation is experimentally shown to grow better when using NPC with improved structure. Prospects of VUV converter on a single NPC are discussed. NPCs of SBO are demonstrated to be useful for autocorrelation diagnostics both in random QPM geometry and in the geometry of nonlinear diffraction from virtual beam.
