Abstract
By mixing tunable diode laser radiation and CO2 laser radiation, wide-band heterodyne signals were generated for precise frequency-response measurements of fast infrared detectors. Measuring capability of frequency range over 1 GHz was demonstrated using HgCdTe and Ge(Ga) detectors. The system operated at 10 µm proved efficiently applicable even to far-infrared detectors.Keywords
