Abstract

What is to the authors' knowledge the first experimental demonstration of a nonresonant cw Raman laser pumped by a tunable external-cavity diode laser (ECDL) is presented. The ECDL is phase-frequency locked to a high-finesse Raman laser cavity containing diatomic hydrogen (H2) by the Pound–Drever–Hall locking technique. The Stokes lasing threshold occurs at a pump power of 400 ± 30 μW, and a maximum photon conversion efficiency of 12.0 ± 1.3% is achieved at 1.6 mW of pump power. A 40-nm tuning range of the cw Stokes emission, 1174–1214 nm, is obtained by tuning of the wavelength of the ECDL pump source.
