The switching dynamics of photothermal-induced absorption optical bistability is studied in CdS. The bistable element being held near its switching threshold is switched by a pulse of an excimer laser, which can be regarded as δ shaped in time with respect to the thermal relaxation time of the sample. The dynamics of the switching process is influenced by the transverse relaxation of the temperature in the sample. Under appropriate conditions either a slowing down or a fast switching is observed.
