Abstract

The system described here uses a CO2-TEA-laser that operates at 2pps with a pulse peak power greater than 300KW. Independent optical trains are used with a transmitted beam divergence of 0.5 mrad and 5-inch diameter receiving optics. A high-speed HgCdTe photodiode with a responsivity of a D* = 1.34 x 10 'cm Hz 2/W is used in the straight detection mode for detecting the leading edge of the pulse return from the target. The unit has been field-tested and range data from many natural and man-made targets has been obtained.
