title: Second-harmonic and sum-frequency generation in ZnGeP(2).
abstract: ZnGeP(2) has been found to be phase matchable for type-1 second-harmonic generation of a CO(2) laser to as high as 10.78 mum at 20.0 degrees C. The Sellmeier equations and nonlinear optical constant of this crystal are reported.
