Mid-infrared Raman laser based on silica fiber is demonstrated. Hollow-core silica fiber filled by the mixture of H-1(2) and D-2 gases was used as an active medium. Pumped by nanosecond pulses of a high-power Er-doped 1.56 mu m fiber laser, the Raman laser generates radiation at 2.9, 3.3, and 3.5 mu m wavelength, which depends on gas composition and pump power. Quantum conversion efficiency as high as similar to 10% is achieved. The possibilities to optimize the performance of the Raman laser are discussed.
