We report the amplification of a low-power 4-mW microchip Nd:YVO4laser at 1064 nm, passively Q-switched with a semiconductor saturable absorber mirror (SESAM). An end-pumped two-stage amplifier module with small-signal gain of 56 dB has been designed to boost the power, generating 6 W at 550 kHz with 100-ps pulses andM2= 1.2. Second-harmonic generation in critically phase-matched LBO yielded 3 W at 532 nm, with pulse stability comparable to that of the fundamental frequency.
