Abstract

A compact diode-pumped high-pulse-energy Yb:GdCa4O(BO3)3 laser passively Q-switched with a Cr4+:YAG saturable absorber is demonstrated at room temperature. An output power of 1.05 W is generated at a pulse repetition rate of 2.5 kHz when the pump power absorbed is 7.7 W, with a slope efficiency determined to be 40%. The laser pulse generated is 10.0 ns in duration, with pulse energy as high as 420 μJ and peak power amounting to 42 kW.
