Abstract: An eye safe 1.57μm OPO laser rangefinder has been developed.Outdoor ranging tests indicate that the range distance is up to 7050m under ~10km visibility,with range accuracy±5m,PRF 20Hz.The rangefinder uses a compact KTP 1.5 7μm single resonator OPO pumped by a water cooling flash lamp pumped EO switched (Ce,Nd):YAG laser.The output of the laser rangefinder is 12mJ/pulse and the pulse width is about 6ns.The receiver uses an InGaAs PIN detector.
