Abstract
We report the efficient continuous-wave (CW) and Q-switched laser operation of a diode-pumped Yb:YVO4 laser. A CW output power of 1 W with a slope efficiency of 59% with respect to absorbed pump power was demonstrated. Passively Q-switched with a Cr4+:YAG saturable absorber, a Yb:YVO4 laser with Raman conversion was demonstrated. Q-switched 18.7-μ J pulses with a pulse duration of 17 ns and a peak power up to 1 kW were obtained at 1018-nm fundamental wavelength and 3.6-μ J pulses with a pulse duration of 6 ns and a peak power of about 0.6 kW were obtained at 1119.5-nm first-Stokes wavelength.
