He-Hg+ and He-Cd+ Lasers

Abstract

Laser oscillation in ionized metal vapors in wide spectral range (from UV to IR) is known to date. Different type of gas discharges are used for metal ion laser excitation - continuous wave and pulsed positive column discharge; continuous wave and pulsed hollow cathode discharge; high frequency discharge and electron beam excitation. Each of these discharges has its advantages and drawbacks. An investigation is needed in metal vapor ion laser development involving new methods for excitation of this laser class.
