Abstract: An upconverting receiver for modulated radiation at a carrier wavelength of 10.6 micrometers and a tunable parametric oscillator operating in the infrared portion of the spectrum are disclosed, in each of which a zinc germanium phosphide (ZnGeP2) crystal is employed as the interaction medium and is pumped by a laser operating substantially at 1.06 micrometers in the infrared in a direction substantially normal to the optic axis. This crystal is presently unique in providing phase matching nearly normal to the optic axis for sum frequency upconversion from a signal wavelength of 10.6 micrometers.
