Abstract
Continuous-wave operation of a diode-pumped Nd:YVO4 laser with self-frequency Raman conversion is demonstrated. The threshold of Raman generation was measured to be 1.3 W of laser diode power. The maximum output power of Stokes radiation at the wavelength of 1177 nm was up to 50 mW at a laser diode pump power of 2.3 W, corresponding to the slope efficiency of 5%. The beam quality M2 of the Stokes radiation was about 1.4. The fluctuations of the Stokes power were minimised down to 4%.
