Abstract
The Raman gain spectra of millimeter thick As2S3 and As24S38Se38 glasses and Ge( 23 - x) GaxSb7S( 70 - y) Se-y with x = 0 and 5 and y = 0, 2, 5 have been measured using a direct nonlinear optics technique. The pump light originated from a picosecond Nd:YAG laser operating at 1064 nm and a tunable optical parametric generator and amplifier ( OPG/OPA) was used as a source for the probe light. A peak material Raman gain coefficient of ( 155 +/- 11) x 10(-13)m/W has been measured for the As24S38Se38 glass. A reversible photodarkening effect which responds to picosecond pulses is also reported. Finally, surface optical damage threshold measurements were found to be less than 9 GW/cm(2) for the reported samples, values which are comparable to some TeO2-based glasses with lower nonlinearities.
