Absorption saturation in commercial and quantum-confine CdSexS_1−x-doped glasses

Abstract

The optical nonlinearity of commercial and experimental CdSexS1−x glasses has been studied using a single-beam absorption saturation technique employing 1−5-psec pulses. Glasses showing strong three-dimensional quantum-confinement 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 non-quantum-confined glasses. Within the range 0.48 < x ≤ 1.0, little difference in nonlinearity was observed.
