Abstract
Described herein is a technique for generating 16 .mu.m laser radiation from a CO.sub.2 molecular gas laser system by use of the 02.sup.0 0-01.sup.1 0 vibrational transition of CO.sub.2. The technique employs a system for pumping the CO.sub.2 molecules from the ground state to the 00.sup.0 1 vibrational energy level such that a population inversion is created between the 00.sup.0 1 and 02.sup.0 0 energy levels, and transferring the population of CO.sub.2 molecules from the 00.sup.0 1 level to the 02.sup.0 0 vibrational energy levels by stimulated emission in a time less than the collisional deactivation time of the CO.sub.2 molecule in the 02.sup.0 0 level. This transfer creates a population inversion between the 02.sup.0 0 and the 01.sup.1 0 vibrational energy levels of the CO.sub.2 molecule which results in 16 .mu.m laser radiation. A similar technique for generating 14 .mu.m laser radiation from a CO.sub.2 molecular gas system is achieved by use of the 10.sup.0 0-01.sup.1 0 vibrational transition.
