Abstract

We describe a compact all-solid-state continuous-wave, singly resonant optical parametric oscillator (SRO) based on periodically poled RbTiOAsO4. The SRO is pumped at 1.064 microm by a Nd:YVO4 laser, which is itself pumped by a 3-W diode laser. Using the intracavity technique produced an oscillation threshold for the SRO of only 1.6 W (diode-laser power). For 3 W of diode pump power some 65 mW was obtained in the (nonresonant) idler (wavelength 3.52 microm). Temperature tuning over the range 10-100 degrees C resulted in tuning ranges of 1.52-1.54 and 3.41-3.54 microm for the signal and the idler waves, respectively. Importantly, relaxation oscillations were absent.

摘要

我们描述了一种基于周期性极化铷钛砷酸盐（RbTiOAsO4）的紧凑型全固态连续波单共振光学参量振荡器（SRO）。该SRO由Nd:YVO4激光器在1.064微米波长处泵浦，而Nd:YVO4激光器本身由一个3瓦的二极管激光器泵浦。采用腔内技术使得SRO的振荡阈值仅为1.6瓦（二极管激光器功率）。对于3瓦的二极管泵浦功率，在（非共振）闲频光（波长3.52微米）中获得了约65毫瓦的功率。在10 - 100摄氏度范围内进行温度调谐，信号光和闲频光的调谐范围分别为1.52 - 1.54微米和3.41 - 3.54微米。重要的是，不存在弛豫振荡。
