Abstract
Organic transfer laser method and means are disclosed employing a gas mixture which includes an acceptor gas comprising an organic molecular vapor, and a donor gas comprising a noble gas or a group II B transition metal, such as mercury, in the vapor state. The donor gas atoms are excited to high energy metastable and/or excimer states by electron beam excitation or electron beam initiated-sustainer discharge type exciting means. Collisional transfer of electronic excitation from the excited donor gas to the lasing organic molecules takes place for excitation of organic molecules to excited singlet states in sufficient number to establish a population inversion in the electronic energy levels thereof for lasing. Depending upon the mixture employed, the laser is tunable over the visible and ultraviolet regions of the electromagnetic spectrum. Operation at high peak power levels with high efficiency is possible.
