Abstract
Fast nanosecond switching times in ZnSe bistable nonlinear interference filters have been reported previously. The samples were excited by a cw holding argon laser and a pulsed excimer laser. In this paper, the pulse energy dependence of the switching time is studied. It appears that the pulse energy must be chosen precisely to obtain optimum performances of the device. Since the switching is related to a "thermal" shift of the interference fringe towards the argon laser wavelength, a three-beam experiment has been performed to investigate simultaneously the spectral shift of the fringe and the switching dynamics. © 1987.
