An ultracompact, actively Q-switched optical parametric oscillator (OPO) has been realized that is only 30 mm in length, based on a semimonolithic microchip laser, a quadrupole deflector, and a monolithic periodically poled lithium niobate crystal. The OPO threshold was 550 mW when Nd:YAG was used as the gain material and 590 mW for Nd:YVO_4, giving signal pulses of as much as 8.7 µJ in energy with Nd:YAG at 1 kHz and 5.9?µJ pulses with Nd:YVO_4 at 5 kHz, for 1.2- and 2-W laser diode pumping, respectively. The output was single frequency and could be tuned over the range 1540–3440 nm. |
