Pulsed infrared difference frequency generation in CdGeAs.sub.2

摘要

The disclosure relates to a laser apparatus for generating a line- tunable pulsed infrared difference frequency output. The apparatus comprises a CO.sub.2 laser which produces a first frequency, a CO laser which produces a second frequency and a mixer for combining the output of the CO.sub.2 and CO lasers so as to produce a final output comprising a difference frequency from the first and second frequency outputs.
