Abstract

A compact and efficient diode-pumped acousto-optically Q -switched intracavity frequency-doubled Nd:Y VO(4)/KTP green laser is demonstrated. With 0.5-at. % Nd:Y VO(4), greater than 4.6 W of 532-nm average power at a repetition rate of 50 kHz was generated with 17-W pump power, corresponding to a conversion efficiency of 27%. At 10-30 kHz the pulse width is shorter than 10 ns, and the peak power is higher than 13 kW.
