Abstract
An experimental device successfully upconverts ir radiation in the 3.2–5.0-µm wavelength range simultaneously to "visible" light at 0.80–0.88 µm, while preserving frequency coding and is thus applicable to ir spectroscopy. The 1.8-µm bandwidth of ir radiation that is upconverted without temperature or phase match tuning is the largest yet reported. The over-all system quantum efficiency of the upconverter/spectrometer system is 0.01% and could be improved to 0.4%.
