Abstract
A detailed description is presented for a tunable far infrared laserspectrometer based on frequency mixing of an optically pumped molecular gas laser with tunable microwave radiation in a Schottkypoint contactdiode. The system has been operated on over 30 laser lines in the range 10–100 cm−1 and exhibits a maximum absorption sensitivity near one part in 106. Each laser line can be tuned by ±110 GHz with first‐order sidebands. Applications of this instrument are detailed in the preceding paper.Keywords
