The kinetics of photoinduced transparency changes has been studied experimentally for amorphous selenium (a-Se) films at different intensities of irradiating 632.8 nm light. The effect of transient reversible photorefraction with comparatively short relaxation time compared to other photoinduced effects is shown to exist in these films in addition to the transient photodarkening phenomenon studied previously.
