Abstract

An external cavity BaWO₄ Raman source pumped by a Q-switched Ho:YAG laser is demonstrated. Watt-level average output power is generated at the first Stokes wavelength of 2602 nm. Output pulse width as short as 8.5 ns was measured at a repetition rate of 5 kHz. Near-diffraction limited beam quality is observed (M²≈1.2). This simplified Raman laser configuration can harness the high average power levels offered by Thulium- and Holmium-doped solid-state and fiber lasers to generate fixed-wavelength and tunable output at 2.3-2.8 μm interval.
