Influence of CO2 pulsed microsecond laser on two-photon absorption (TPA) at wavelengths of Nd:YAG (1060 nm and 1320 nm) and Er glass lasers (1540 nm) for As2Se2S glasses was studied. Dependence of the TPA versus the photoinducing power densities at wavelength 9.2 ?m is studied. The highest values of the TPA ? coefficient were achieved for perpendicular polarizations between the pumping and probing laser beams. The obtained values of TPA coefficients indicate a possibility of using the As2Se2S glasses as optically-operated IR laser limiters in a wide spectral range. The substantial role of anharmonic electron-phonon subsystem is demonstrated.
