Multikilowatt mid infrared emission with high pump photon conversion efficiency ( about 15 percent) has been obtained by difference frequency generation in CdGeAs/sub 2/ utilizing the double wavelength output from a grating tuned twin-cavity TEA CO/sub 2/ system, one signal of which is frequency doubled to provide efficient synchronized sources for both pump and idler. Tuning over a spectral range 8-14 ..mu..m can be achieved and further extended to 17 ..mu..m using 12.8 ..mu..m emission from an efficient TEA CO/sub 2/ pumped NH/sub 3/ laser.
