Design criteria for high power laser systems
Abstract
The basic limitations of glass laser systems are examined and approaches are discussed for overcoming these limitations. A major limitation regarding maximum beam intensity is related to the effect of the nonlinear index of refraction of the glass on beam propagation. Short pulse laser systems must be designed with large area, high gain amplifiers utilizing glass for which the nonlinear index of refraction has a low value. Aspects of laser amplifier design are investigated, taking into account rod amplifiers, disk amplifiers, and the so-called 'active mirror amplifier'.
