Fast response of PLZT pyroelectric detectors to megawatt CO2laser pulses

PLZT ceramic was used to make fast pyroelectric detectors. These detectors were able to: 1) respond to 10 ns events; 2) directly drive a 50 Ω CRO input with load resistors as small as 10 Ω; and 3) withstand irradiation with CO

without cracking or need for repoling. The performance characteristics are described and are found to be in general agreement with a previously developed analysis.
