New SMMW laser transitions optically pumped by a tunable CO2 waveguide laser
Abstract
Optical pumping of a submillimeter wave (SMMW) laser with a relatively compact RF-excited CW CO2 laser is described. The increased frequency tunability of the waveguide pump laser has resulted in new low threshold SMMW emissions in C2H2F2, CDF3, and CD2F2 by pumping into absorption lines which are beyond the tuning range of a conventional CO2 laser. Frequency offsets and some assignments obtained with the aid of a tunable diode laser heterodyne spectrometer are reported.
