We report on an optical parametric oscillator (OPO) that is synchronously pumped directly by a diode laser. This laser is an actively mode-locked master-oscillator power-amplifier system that produces 20-ps pulses at 927 nm with a repetition rate of 2.5 GHz and an average power of 0.9 W. The OPO, which is a singly resonant device based on periodically poled lithium niobate, generates 7.8-ps pulses. The OPO threshold is 300 mW of average pump power, and the maximum average idler output power is 78 mW at a wavelength of 2100 nm. By changing the crystal temperature we can wavelength tune the output in the ranges 1530-1737 nm (signal) and 1986-2348 nm (idler). Rapid wavelength tuning of the OPO over 46 nm (signal) and 74 nm (idler) is achieved through tuning the cavity length over 28 microm by use of a piezoelectric transducer.
我们报道了一种由二极管激光器直接同步泵浦的光学参量振荡器（OPO）。该激光器是一个主动锁模主振荡器功率放大器系统，它在927nm波长产生20ps脉冲，重复频率为2.5GHz，平均功率为0.9W。该OPO是基于周期性极化铌酸锂的单谐振器件，产生7.8ps脉冲。OPO阈值为300mW平均泵浦功率，在波长2100nm处最大平均闲频输出功率为78mW。通过改变晶体温度，我们可以在1530 - 1737nm（信号光）和1986 - 2348nm（闲频光）范围内对输出进行波长调谐。通过使用压电换能器将腔长调谐28微米，实现了OPO在46nm（信号光）和74nm（闲频光）范围内的快速波长调谐。
