Abstract
We present experimental data and the underlying physics of spatial-phase-modulation effects associated with the thermal nonlinearity of semiconductor-doped glasses. Transient and steady-state self-focusing, laser-induced birefringence, and spatial ringing of the thermal origin were studied in this class of optical materials.
