Abstract
By means of two-beam experiments, the transmission properties of highly excited GaSe crystal of different thicknesses (2 micrometers to 1.5 mm) have been investigated in the fundamental absorption and free exciton region. Induced transmission was observed in the whole considered region for lower pump intensities. Results of bistability in an entire ZnTe thin films are present for the first time.
