EFFICIENT SUMMATOR BASED ON STBS NONLINEA RITY

Possibilities of STBS-based summators were studied up to pump intensit ies approximately 0.2 GW/cm2 for an energy approximately 15 J and wave length 1.06 mum. A simple numerical criterion was obtained to assess t he stability of a laser system consisting of a master oscillator , amp lifiers, and a summator. The analysis of spurious noise of the summato r was made. It was experimentally shown that the summator had an energ y efficiency of approximately 0.8 with the invariable diffractive dive rgence of the amplified signal. Experimental operation of the summator in the periodic-pulse regime was simulated.
