With Nd:CTGS crystal as self-frequency-doubling (SFD) medium, and Cr4+:YAG crystal as passively Q-switcher, a pulsed microchip green laser was demonstrated. The maximum average output power was 69 mW, and the corresponding pulse duration, repetition rate, single pulse energy, and peak power were 7.12 ns, 8.83 kHz, 7.81 μJ, and 1.01 kW, respectively. As we have known, they are the best results of diode pumped, pulsed SFD laser, and the simple structure, miniaturization, as well as low cost are very favorable for large-scale production and application.
