Efficient multikilowatt mid infrared difference frequency generation in CdGeAs2
Abstract
Multikilowatt mid-infrared emission with high pump photon conversion efficiency (approximately 15 percent) has been obtained by difference frequency generation in CdGeAs2 utilizing the double wavelength output from a grating tuned twin-cavity TEA CO2 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 microns can be achieved and further extended to 17 microns using 12.8 microns emission from an efficient TEA CO2 pumped NH3 laser.
