Doppler Velocimeter for Laser Accelerated Targets.

Abstract

A doppler velocimeter utilizing a spectrograph and a short pulse laser probe is described which provides good spatial (20 microns) and subnanosecond temporal resolution. This system has been used to measure the velocity profiles of targets ablatively accelerated to very high velocities by a high power laser beam. A unique aspect of this velocimeter is that the doppler wavelength shifts are measured directly rather than employing interferometric techniques. (Author)
