We present results of a theoretical analysis of sum-frequency generation incorporating second harmonic generation of the incident fields. It is shown that under certain conditions, a significant reduction in conversion efficiency can occur even when phase mismatch for second harmonic generation is relatively large. Experimental results on sum frequency generation in CdGeAs2 of two CO2 laser emission tuned to the 9 µm vibrational band are presented which are in good qualitative agreement with the theoretical predictions. © 1986.
