Abstract

This review paper presents in summarized form the results of a thorough basic research on EDMG physics and applications to gas-flow discharge lasers, as well as an analysis of the world state of the art in this field. The fundamental physical idea of the paper is based on a conclusion that the CW EDMG is a new form of gas discharge, different from the classical glow discharge. The CW EDMG plasma is inhomogeneous in the current direction; in many cases it is substantially unstable. The paper contains a survey of experimental data, analytical models and numerical analysis of the EDMG. It gives a possibility of estimating the main electrical and power input properties of fast-flow gas discharge lasers. One of the most important physical and practical achievements of the R&D is a possibility of dramatic increase (up to atmospheric range) of EDMG working pressure. The paper might be of interest to physicists and engineers in the fields of laser and electrical discharge techniques, as well as for ecological and plasma-chemical applications.
