EXTENSION OF LASER HARMONIC-FREQUENCY MIXING TECHNIQUES INTO THE 9 μ REGION WITH AN INFRARED METAL-METAL POINT-CONTACT DIODE

Abstract

An infrared point-contact diode is used to mix the frequency of a 28.0 μ water laser with that of a 9.3 μ CO2 laser and a K-band microwave radiation. The experiment provides, among several applications, the crucial link necessary to establish a frequency multiplier chain for absolute frequency measurements in the infrared.
