Efficient high-power diode-end-pumped TEM00 Nd : YVO4 laser with a planar cavity

Abstract

We demonstrate a compact and efficient diode-end-pumped TEMinfinity laser with output power of 30 W for 48 W of incident pump power by use of two coated Nd:YVO4 crystals to form a thermally stabilized flat-flat cavity. In Q-switched operation 25 W of average power at a pulse-repetition rate of 100 kHz and similar to 0.9-mJ pulse energy at a pulse-repetition rate of 10 kHz were produced.
