The frequency components of an input pulse are dispersed into divergent respective rays that are applied to an acousto-optic modulator after being collimated. The amplitude of each frequency component emerging from the modulator is determined by the amplitude and phase of a grating formed therein by modulated radio frequency wave applied to it. The parallel rays emerging from the modulator are focussed onto a device for forming an output pulse.
