Enhanced Backscatter with a Structured Laser Pulse.

Abstract

A large amplitude backscatter instability, consistent with Brillouin, occurs when a prepulse plasma is formed ahead of a high irradiance (10 to the 15th to 10 to the 16th power W/sq cm) Nd-laser pulse. These results indicate that temporally structured laser pulses suggested for laser pellet implosion may also encounter large backscatter. (Author)
