STIMULATED RAMAN GAIN COEFFICIENTS FOR Li6NbO3, Ba2NaNb5O15, AND OTHER MATERIALS

Abstract

The available gain for stimulated Raman scattering has been computed from measured values of absolute spontaneous Raman scattering cross sections at 300° and 80°K for various materials including Li6NbO3 and Ba2NaNb5O15. The power gain coefficients and power required for 1% gain per pass with confocal geometry at λ = 1.065 μ are tabulated for the more promising materials. Operation of a CW or quasi-CW Raman oscillator appears feasible, particularly with the most efficient material, Li6NbO3.
