Power output enhancement of a laser-produced Cd plasma recombination laser by plasma confinement

Abstract
Enhancements of over a factor of 22 in power output and a factor of 130 in energy output of a laser‐produced Cd plasma recombination laser have been achieved by using guides to confine and elongate the plasma and control its cooling. Such techniques may prove useful in increasing the efficiency of recombination lasers and also in enhancing the prospects of scaling these devices to shorter wavelengths.
