Study of the laser performance of a novel mixed Nd:Y0.8Lu0.2VO4 crystal

We present for the first time a diode end‐pumped acousto‐optic (AO) Q‐switched Nd:Y0.8Lu0.2VO4 crystal laser with a comparative planar‐planar cavity in this paper. The maximum continuous wave (CW) power of 5.61 W is achieved at the incident pump power of 13.07 W with 20% transmission for the output...

Zusammenfassung:	We present for the first time a diode end‐pumped acousto‐optic (AO) Q‐switched Nd:Y0.8Lu0.2VO4 crystal laser with a comparative planar‐planar cavity in this paper. The maximum continuous wave (CW) power of 5.61 W is achieved at the incident pump power of 13.07 W with 20% transmission for the output coupler, resulting in an optical‐to‐optical conversion efficiency of 43%. For Q‐switching operation, at the incident pump power of 13.07 W and 1 kHz repetition rate, the shortest pulse width of 11 ns is measured and the highest peak power of 225.45 kW is obtained for the output transmission of 50%. At 100 kHz repetition rate and 20% output transmission, the maximum average output power of 4.23 W is reached. (© 2010 by Astro Ltd., Published exclusively by WILEY‐VCH Verlag GmbH & Co. KGaA)
