基于1.5微米放大二极管激光器和连续波掺铥光纤激光器的差频产生，在取向图（OP） GaAs中开发了窄线宽中红外光源，并对其光谱应用进行了评估。光源可以调谐到7.6-8.2微米范围内的任何频率，输出功率为0.5 mW。OP-GaAs样品的测量特性证明了该材料的高质量。
A narrow-linewidth mid-IR source based on difference-frequency generation of an amplified 1.5 microm diode laser and a cw Tm-doped fiber laser in orientation-patterned (OP) GaAs has been developed and evaluated for spectroscopic applications. The source can be tuned to any frequency in the 7.6-8.2 microm range with an output power of 0.5 mW. The measured characteristics of the OP-GaAs sample demonstrate a high quality of the material.
