摘要：

For the first time broadband sum frequency generation in ZnGeP2 crystal has been accomplished with a compact cryogenic slab RF discharge CO laser. The spectrum of the CO laser operating in a repetitively pulsed multiline Q-switching mode consisted of similar to 90 emission lines in the wavelength range of 4.95-6.60 mu m. Internal sum frequency generation efficiency was reached up to 8.2%. The resulted spectrum contained similar to 200 spectral lines in the wavelength range of 2.5-3.2 mu m.
