Electric discharge pumping in laser

WebFeb 11, 2015 · The difficulty is to find a system with appropriate levels such that state $ 2\rangle$ is unstable and cannot be thermally populated. For temperatures above 10000K you can think of excimer lasers - normaly they are pumped by a strong electric discharge, but if you imagine another way of heating the gas to such temperatures, it could also work.
