High-efficiency continuous-wave Raman laser pumped by an injection-locked broad-area diode laser

We report an efficient CW far-off-resonance Raman laser in H/sub 2/ gas pumped by an injection-locked broad-area diode laser. The pump wavelength 794 nm is Raman shifted to the Stokes wavelength 1185 nm. The total output Stokes power reaches 21.6/spl plusmn/0.5 mW and the photon conversion efficienc...

Description
Summary:We report an efficient CW far-off-resonance Raman laser in H/sub 2/ gas pumped by an injection-locked broad-area diode laser. The pump wavelength 794 nm is Raman shifted to the Stokes wavelength 1185 nm. The total output Stokes power reaches 21.6/spl plusmn/0.5 mW and the photon conversion efficiency reaches (74/spl plusmn/10)%.
