Abstract

Induced probe-beam modulation in semiconductor-doped glass was observed. The dephasing between pump and probe modulation is dependent on the pump power, the modulation frequency and the selenium concentration. At room temperature, with a proper choice of these parameters, the dephasing can change from 0° (laser-induced clearing) to −180° (laser-induced darkening). A slow switching behaviour and optical bistability without external feedback are also reported.
