Abstract

We demonstrate a diode-pumped cw Raman laser in H2 with photon-conversion efficiency of 66±8%. Pumped by an injection-locked diode laser at 792  nm, the Stokes laser produces a peak output power of 16 mW at 1180  nm. Accompanying the high Stokes power are deviations from the existing theory, which are believed to be caused by the thermal-lensing effect of the Raman gas.
