Abstract
A diode-pumped, actively Q-switched eye-safe dual-wavelength laser employing ceramic neodymium-doped yttrium aluminum garnet (Nd:YAG) as gain medium and BaWO4 as Raman medium is demonstrated for the first time to the best of our knowledge. The dual-wavelength Raman laser emission at 1502 and 1527 nm is based on the dual-wavelength fundamental laser emission at 1319 and 1338 nm. With a pump power of 17.3 W and pulse repetition frequency of 20 kHz, a maximum dual-wavelength output power of 0.82 W was obtained, comprising a 0.37 W, 1505 nm laser component and a 0.45 W, 1527 nm laser component.
