Abstract
We report intracavity second harmonic (at 532 nm) generation in a passively Q-switched mode-locked Nd:YVO4 laser. The width of a typical Q-switched envelope of the mode-locked pulses for the green laser was around 65 ± 5 ns and the repetition rate for the mode-locked pulses was 400 MHz. The intracavity frequency doubling significantly improves the depth of modulation of the mode-locked pulses. The peak power of a single mode-locked green pulse near the center of the Q-switched envelope was estimated to be more than 2 kW and the average green power was 6 times higher than the CW green power at an incident diode pump power of 6 W.
