High-power dual-wavelength eye-safe ceramic Nd:YAG/SrWO(4) Raman laser operating at 1501 and 1526 nm.
By employing SrWO(4) as a Raman active medium and a ceramic Nd:YAG laser operating at 1319 and 1338 nm as a pump source, an efficient eye-safe dual-wavelength Raman laser operating at 1501 and 1526 nm has been demonstrated. A maximum total output power as high as 3.36 W is obtained under a pump power of 33.3 W and a pulse repetition frequency (PRF) of 30 kHz. The highest optical-to-optical conversion efficiency of 11.2% is achieved at the pump power of 27.3 W. To our knowledge, 3.36 W is the highest output power of a 1.5 μm eye-safe Raman laser.
