Paper Abstract

Laser rangefinders operating at 1. 54 jtm are of increasing interest because of their eyesafe property. We report on technology and hardware developed at Hughes Aircraft Company based on using Stimulated Raman Scattering (SRS) of the Nd:YAG 1. 06 im output to the eyesafe 1. 54 jtm wavelength. This technology has been extended from the 1 Hz repetition rate to the 10 to 20 Hz range for air defense applications by use of circulating gas Raman cells and several resonator configurations have been developed to improve conversion efficiency and beam divergence. The eye safety and the atmospheric penetration of the 1. 54 jim wavelength is discussed.
