Resumen:
We present the construction and characterization of a pulsed OPO. This OPO consists of a periodically poled lithium niobate (PPLN) crystal placed inside a linear, flat mirror, singly-resonant cavity. It is pumped by a Nd:YAG laser that emits pulses of ? = 1.064 ?m, 7 ns, and 1 mJ. The signal can be temperature tuned (25-150°C) from 1.452 to 1.478 ?m, and the idler from 3.81 to 3.98 ?m. The oscillation threshold is reached with only 150 ?J per pump pulse, and at 600 ?J the energy of the signal is 20 ?J per pulse. In addition, we present a technique to indirectly infer the energy of the pulses emitted by the OPO that is based on measuring the temporal distortion the pump undergoes after traversing the resonator.
