The lab uses an optical parametric oscillator to generate tunable infrared light.
实验室使用光学参量振荡器来产生可调谐的红外光。
By adjusting the cavity length and crystal temperature, the optical parametric oscillator can be tuned across a wide range while maintaining narrow linewidth output.
通过调节腔长与晶体温度,光学参量振荡器可以在很宽的范围内调谐,同时保持较窄线宽的输出。
