Two-beam CO2 laser system for laser induced fusion experiments

Abstract

As the only well developed laser system potentially suitable for a laser fusion power system, it is critical that the feasibility of fusion induced by CO2 laser pulses be demonstrated. For the next 2 years (until the 10-kJ 8-beam system at LASL becomes operational), the principal tool for carrying out these investigations will be the Dual Beam Laser System (DBLS). Designed primarily as a prototype for the four modules that will comprise the 10-kJ laser system, DBLS has been upgraded to an experimental target facility by the addition of a high-contrast short-pulse oscillator and the necessary target diagnostic and handling equipment. With target experiments scheduled to begin in the spring of 1976, the DBLS is currently undergoing evaluation to establish its short-pulse performance characteristics.
