Industrial lasers with a technical efficiency higher than the physical efficiency
Abstract
A scheme is proposed whereby the technical efficiency of a laser is increased by extracting useful work from some of the energy expended on the heating of the working mixture in the active volume. Such a laser operates as a heat engine. The proposed approach would permit a severalfold increase in the technical efficiency of lasers operating at temperatures well above room temperature.
