Abstract

We report the active Q-switching of a Yb:Er:YVO4 laser for the first time. A Yb:Er:YVO4 crystal was end pumped by a quasi-continuous wave laser diode emitting at 967 nm with a peak power of up to 48 W. The laser cavity was actively Qswitched using the spinning disc technique. At a repetition rate of 19.2 kHz, the Q-switched slope efficiency and threshold were 4 % and 62 mJ respectively. In comparison, the same system had a slope efficiency of 5% and a threshold of 75 mJ without mechanical Q-switching. Single pulse of energy up to 90 μJ and duration as short as 110 ns were obtained for the single output pulse per pump pulse operation.
