Doppler Velocimeter for Laser Accelerated Targets.

reportActive / Technical Report | Accession Number: ADA089134 | Open PDF

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
