Pagination or Media Count:
Three devices, a short-pulse laser, a coaxial Pockel cell shutter, and a single-crystal transmission-line Pockel cell, have been evaluated as techniques for producing laser pulses approximately 1 nsec in duration. The short-pulse laser has produced pulses that range from 0.5 nsec to 2.0 nsec in duration with peak powers from 25 to 300 kW. Pulses 1.8 nsec in duration FWHM full width at half maximum with risetime of less than 0.4 nsec have been gated from Q-switched ruby laser pulses by the coaxial shutter, while pulses 1.3 nsec FWHM have been obtained in the same fashion with a transmission-line shutter.
