Optimum spectral matching for a resonantly pumped far-infrared laser
Abstract
A new interferometric technique is described for matching the central frequency and bandwidth of a CO 2-TEA laser to a Doppler broadened absorption line in a far-infrared (f.i.r.) medium. Experimental results are presented which demonstrate a tuning range of more than 1 GHz for the TEA laser lines, TEA laser mode structure consistent with a bandwidth less than 100 MHz, and a large increase in f.i.r. laser pumping efficiency. Application of the technique to the realization of a continuously tunable, narrow bandwidth, multi-atmosphere CO 2 laser is discussed.
