Abstract

We report a high-power diode-single-end-pumped continuous-wave and Q-switched Nd:GdVO₄ red laser through intracavity frequency-doubling with a type-I critical phase-matched LBO crystal. The maximum CW output power at 671 nm was measured to be 2.1 W at the incident pump power of 30 W, with the corresponding optical conversion efficiency of 7%. At the repetition frequency of 47 kHz, the maximum average output power of quasi-CW red light was obtained to be 6 W, with the corresponding optical conversion efficiency of 12.8% and the pulse width of about 97 ns. At the average output power around 5 W, the power stability was better than 5.8% for one hour. The M² factor increased from 1.33 to 2.47 when the output power was increased from 1 W to 6 W. At the repetition rate of 25 kHz, the maximum pulse energy of 212 μJ was obtained with the corresponding peak power of 3.98 kW.
