Abstract

We report the observation of cw coherent anti-Stokes emission from a nonresonant cw Raman laser in ${\mathrm{H}}_2.$ The anti-Stokes emission is collinear with the pump and Stokes beams with a Gaussian spatial profile. The external anti-Stokes to Stokes power ratio is 26.3 parts per million when the laser cavity is tuned to the center of the Raman resonance and higher for slight detuning from line center. A steady-state theory is presented that accurately describes the anti-Stokes behavior as a function of output Stokes power and detuning from the Raman resonance.
