Abstract

A TE laser amplifier has a fully closed metal housing. This fact, its geometry, and that of its electrodes (5-7) and/or the reversal of the output polarity make possible a homogenous field distribution, a capability to influence the local amplification process in the laser medium, and a relatively long lifetime of the gas and the laser.
