Various lengths of Yb:Er:YVO4were end pumped by a quasi-continuous wave 967 nm diode laser. The best slope efficiency with respect to absorbed pump power for gain switched operation was 8 % for a 5 mm long crystal. Co:MgAl2O4saturable absorbers of 98 % and 93 % initial transmission were used to passively Q-switch the cavity. For the 98 % initial transmission absorber, average pulses energies of 44 μJ were measured. The average pulse width and repetition rate were ∼256 ns and 36 kHz, respectively. For the 93% initial transmission absorber, a single output pulse of 37 μJ energy and 22 ns duration per pump pulse was measured when the crystal was pumped for a pumping duration of 1.7 ms.
