Paper Abstract

This Paper offers some new views on a Nd:YAG PUMP intracavity Raman frequenc shift laser with high conversion efficiency(27.5X) of the first order of Stokes, which is twice of that with Raman oscillator extracavity. The wave length of PUMP is 1.06um. Raman active medium is methane gas(65-75atm). The output of the device is main the first order of Stokes(1.54μm), no PUMP at all. A new ideal model, optimal design for Raman cavity, and theoretical analysis are presented in this Paper. The result of our theoretical calculation is near consistent withthat of experiment. The eyesafe laser rangefinder with the Nd:YAG intracavity Raman oscillator arrangement has not been covered in the international documents.
