报道了一种基于电流控制的KTiOPO4(KTP)光参量振荡器的波长灵敏的中红外(IR)ZnGeP2(ZGP)光参量振荡器(OPO)。在保持ZGP晶体角度不变的情况下，通过改变KTP OPO泵浦波长来调谐中红外波长。利用电流计改变晶体角度，实现了KTP OPO的快速调谐。我们的中红外光源可以跳转到不同的波长，而不需要扫描中间波长，同时还允许连续波长扫描。中红外光源的调谐范围约为5~10微米，相位匹配角为51度，泵浦波长控制在1.95~2.2微米范围内。(C)2007年美国光学学会。
A wavelength-agile mid-infrared (IR) ZnGeP2 (ZGP) optical parametric oscillator (OPO) using a galvanocontrolled double-crystal KTiOPO4 (KTP) OPO was demonstrated. The mid-IR wavelength was tuned by varying the KTP OPO pump wavelength while the ZGP crystal angle remained fixed. Rapid tuning of the KTP OPO was achieved by changing the crystal angle by using the galvano scanner. Our mid-IR source can jump to a different wavelength without scanning through the intermediate wavelengths while also permitting continuous-wavelength scanning. The mid-IR source can be tuned from approximately 5 to 10 mu m at a phase-matching angle of 51 degrees, while the pump wavelength is controlled in the 1.95-2.2 mu m range.
