An electrooptic shutter based on the use of the longitudinal rockels effect in DKDP crystals with a kw non-active loss was devised. Due to concentration of the controlling electric field on a short crystal portion the modulating element length could be reduced by a factor of 1.5-2 as compared to the length in the known constru-ctions. The shutter was applied to a ruby laser used in framed shutterless high-speed cinematography in order to generate a lighting pulse train. For controlling the mode composition of the generation of a laser with a plane geometry cavity a space-time light modulator which is a combination of the shutter and a smooth edge diaphragm was developed. The modulator has comparatively low non-active loss and can control the spatial development dynamics of the laser generation. It's use may be of interest for the purpeses of high-speed motion-picture holography.
