A wavelength-agile mid-infrared (IR) Zn Ge P 2 (ZGP) optical parametric oscillator (OPO) using a galvano-controlled double-crystal K Ti O P O 4 (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 μ m at a phase-matching angle of 51°, while the pump wavelength is controlled in the 1.95 2.2 μ m range.
