Abstract

We report on the laser performance of a diode-pumped Yb:KGd(WO4)(2) laser that is passively Q switched with a Cr4+:YAG saturable absorber. Raman conversion of fundamental laser emission in the laser crystal was demonstrated. Q-switched 3.4-mu J pulses with a pulse width of 85 ns were obtained at the 1033-nm fundamental wavelength and 0.4-mu J pulses with a pulse width of 20 ns were produced in a first Stokes at 1139 nm.
