We present a dynamic theory related to experiments on the induced transmission of doped CdS crystals under pulsed laser excitation at 2 K at frequencies just below the band gap. Numerical simulations of the optical switching front which describes the non-linear spatio-temporal dynamics of the switching process from low to high transmittivity and back are performed for two different two-level models. These are associated with two different bleaching mechanisms of the acceptor–conduction band transition.
