Abstract

Pyroelectric detectors have been developed at Los Alamos National Laboratory (LANL) for use with high-frequency applications such as laser fusion. Less than 50-ps total response time devices have been measured. The voltage responsivity with a 50-0 load is about 5 to 10 V/MW, requiring 10 to 20 mJ/cm2 to produce 1 -V, 1-ns pulses. The latter are 1 mm2 in area. High-speed devices with up to 1 cm2 area have been developed. A novel method of fabrication now permits voltage responsivities up to 50 V/MW with a 50-0 load. This improved sensitivity detector is slower than the fastest design but is still suitable for measuring 1-ns pulses.
