✦ Synopsis

The optical nonlinearity of commercial and experimental CdSexS,-, glasses has been studied using a single-beam absorption saturation technique employing 1-5-psec pulses. Glasses showing strong three-dimensional quantumconfinement effects were found to be more difficult to saturate than glasses with larger crystallites that exhibit bulk crystallike optical properties. The effect of anion stoichiometry on the nonlinearity was also studied in nonquantum-confined glasses. Within the range 0.48 < x < 1.0, little difference in nonlinearity was observed.
