Title: High-energy Nd:glass laser system for Thomson scattering diagnosis of high-temperature and low-density plasmas

Abstract

The determination of temperature of electron density of reactor-grade fusion plasmas (T>5 keV, Ne> or =10/sup 13/ cm/sup -3/) will require enhanced capability in Thomson scattering diagnostics. While improved detection systems will help, it is clear that the scattered population must be increased because of the excessive thermal broadening. The system described here has a Nd:glass oscillator followed by three stages of amplifier. At present, the system generates a 60 J single pulse with beam divergence less than 0.6 mR. This pulse can be used with a KDP-II frequency doubler to generate 30 J pulses of 1.06 and 0.53 ..mu..m.
