“…Optical second-harmonic generation (SHG) induced by an acoustical field was observed in several composites, both in bulk as well as in large sized nanocrystallite samples [1,2]. The effect is generally explained by a noncentrosymmetric spatial charge density distribution of photocarrier excitation under an external acoustical field [3] due to electrostriction (photoacoustical) effects.…”

Single crystals of zinc magnesium tetra thiocyanate [ZnMg(SCN) 4 ], a bimetallic thiocyanate complex, were grown by slow evaporation solution growth technique at room temperature. The bright, transparent and colourless crystals have well defined faces. The grown crystals were characterized through elemental analysis, powder X-ray diffraction (XRD), thermogravimetric (TG) and differential thermal analysis (DTA), differential scanning calorimetric analysis (DSC), Fourier Transform Infra red (FTIR) and Optical studies. The elemental analysis confirms the stoichiometry of the synthesized crystals. The compound crystallizes under monoclinic structure with lattice parameters a = 10.055 Å, b = 7.44 Å, c = 6.00 Å and β = 90.113°. The TGA indicates 25 % weight loss at 205°C from which the decomposition pattern is formulated. The DSC study indicates that the crystal undergoes only first order phase transitions. The FTIR spectrum indicates among others the presence of metal-nitrogen and metal-sulphur bonds thus confirming the formation of the complex. The second harmonic-generation (SHG) was confirmed by the emission of green radiation using Nd: YAG laser.

“…For the off-diagonal second-order susceptibilities this maximum is shifted towards higher acoustical powers. This fact may indicate on the presence of electron-acoustical-phonon interactions of higher orders [2,3]. We present the AIOSHG behavior corresponding to the maximal output AIOSHG achieved at low temperature and acoustical frequencies about 12 kHz.…”

“…Since the discovering of the acoustically induced optical second harmonic generation (AIOSHG) by Nelson and Lax [1], AIOSHG has been revealed in several composites [2,3]. One of the physical origin of the AIOSHG is a spatial asymmetry of photocarrier excitation under external acoustical power [4].…”

Acoustically induced optical second harmonic generation (AIOSHG) in InAs single crystals was investigated. With increasing acoustical power, the AIOSHG for fundamental CO laser light (λ=7.1 µm) increases and achieves its maximum value at acoustical power density about 1.70 W/cm 2 . The value of the AIOSHG for InAs was substantially higher than for key inorganic photo-refractive and ferroelectrics materials. With decreasing temperature, the AIOSHG signal strongly increases below 42 K. The AIOSHG maxima were observed at acoustical frequencies ranged at 7-11 kHz. Comparing the obtained results with the acoustically induced IR spectra at low temperature, one can conclude that the observed effect is associated with acoustically-induced phase transformations.

Two-photon absorption of Tl_1-xIn_1-xSn_xSe₂nanocrystallites

Abstract. Novel materials for the infrared two-photon absorption -Tl 1-x In 1-x Sn x Se 2 single crystals (x=0.1,0.2) were grown. Two-photon absorption (TPA) was studied at CO 2 laser wave-length 9.4μm with pulse duration 1μs. The studies were performed at different temperatures and for the nanocrystallite sizes varying within the 7-200 nm. The studies have shown that the TPA may be enhanced during the decrease of the nanocrystallite sizes below 50-60 nm. There exists also some critical x value at which the TPA value begin substantially to increase. The studied nanocrystallites are relatively stable to the infrared laser treatment and are not hygroscopic which allow to use them in different IR optoelectronic devices.
