Efficient high-power diode-end-pumped TEM00 Nd : YVO4 laser

Abstract

We demonstrate a compact and efficient diode-end-pumped TEM00 laser with output power of 25.2 W for 52 W of incident pump power by use of a single YVO4 crystal with a Nd concentration of 0.3 at.%. In Q-switched operation 21-W of average power at a pulse repetition rate of 100 kHz and similar to 1.1-mJ pulse energy at a pulse repetition rate of 10 kHz were produced, At 10 kHz, the pulse width is around 10 ns and the peak power is higher than 100 kW.
