    • A method for thermally stabilizing an optical parametric oscillator (OPO) 10 to maintain constant optical path length for stable high power output places a beam dump 32 outside an OPO cavity 18. The OPO 10 has a nonlinear crystal 22 within cavity 18 for splitting a single input pump beam 14 into lower energy signal and idler beams 16, 18. The method includes providing a cavity exit port for unconverted pump and generated idler beams, and absorbing unconverted beams in beam dump 32. The method includes athermalization by actively cooling surfaces used as an optics mounting base, and athermalization by constraining the size of cavity 18 by using thermally stiff members, guiding pins or rails, or by using bimetallic materials with different expansion.
    • 用于热稳定光学参数振荡器(OPO)10以保持用于稳定的高功率输出的恒定光程长度的方法将光束转储32放置在OPO腔18外部。 OPO 10具有腔18内的非线性晶体22,用于将单个输入泵浦光束14分成较低能量信号和惰轮16,18。 该方法包括提供用于未转换的泵和产生的惰轮的空腔出口端口,以及在梁式收集器32中吸收未转换的梁。 该方法包括通过主动冷却用作光学安装基座的表面的绝热,以及通过使用热刚性构件,引导销或轨道或通过使用具有不同膨胀的双金属材料约束腔18的尺寸来进行绝热。
