本文叙述了在磷酸钛氧钾中，利用两种连续环形激光辐射的差频混频产生可调谐窄带中红外光。该系统产生的红外功率为1.20 µW的差频光在1.05至2.8 µm（3500-9500 cm-1）范围内连续可调。在100 cm-1的范围内连续扫描，光谱精度优于10 MHz（0.0003 cm-1）。利用固体仲氢晶体的一部分Q2（0）泛频振转光谱，对激光系统的高分辨特性进行了评价。
The generation of tunable narrow-band mid-infrared light by difference-frequency mixing of two kinds of continuous-wave ring-laser radiation in potassium titanyl phosphate is described. The system produces infrared powers of ∼20 µW of difference-frequency light continuously tunable from 1.05 to 2.8 µm (3500–9500 cm-1). Continuous scans over a range of 100 cm-1 with a spectral precision better than 10 MHz (0.0003 cm-1) are achieved. The high-resolution characteristics of the laser system are evaluated by use of a portion of Q2(0) overtone vibration–rotation spectrum of a solid parahydrogen crystal.
