Photoinduced optical phenomena in amorphous Sb₂Se₃- BaCl₂-PbCl₂ glasses have been studied using experimental spectroscopic and theoretical quantum chemical methods. Photo-induced two-photon absorption (TPA) and second harmonic generation (SHG) were measured for the probing CO₂-laser wavelength 10.6 micrometers . CO-laser ((lambda) equals 5.5 micrometers ) was used as a source of photoinducing light. We have found that with an increasing CO-laser exposure the SHG maximum output signal increases and achieves its maximum values at CO photon fluence 18 * 10¹³ phot./cm² after the two hours of illumination. The absolute SHG values were not more than one order less comparing with ZnS crystals in case of its third rank nonlinear optical susceptibility tensor components (chi) ₂₂₂ ((lambda) equals 10.6 micrometers ). With decreasing temperature the SHG signal strongly increases within the 32...26 K temperature range. Time-dependent probe-pump measurements indicate on existence of SHG maximum at time delay about 45 ps. Good correlation between SHG and TPA was observed. Simultaneously spectra positions of TPA maxima are strongly depended on the photoinduced fluence. Contrary to the SHG behavior for the TPA we observe at least two maxima at 26 ps and 70 p.s We explain this dependence within a framework of the quantum chemical approach with taken into account of anharmonic electron-vibrational interaction. Coming out from the performed calculations and IR-spectroscopy Fourier technique measurements in the spectral region between 100 cm^-1 and 300 cm^-1 we have ascertained a key role of Sb-Se fragments in the observed photoinduced effects. A stage of the reversible photoinduced changes is realized after first cycle of IR photoexposure and thermoannealing. We have compared also the different existing models of the photoinduced changes. The results also show that the observed materials have relatively low non-uniformity through the specimen surfaces and can be used as a powerful tool for investigations of picosecond IR laser processes.
