CW Pin Discharge Laser

Abstract

The results of a study on a Continuously Operating Fast Flow Electrically Excited (COFFEE) laser excitation concept are reported. The concept uses a multipin-to-plane electrode configuration with transverse gas flow to produce a high-pressure, self-sustained glow discharge. Emphasis is placed on developing the glow discharge scaling criteria. Both theoretical and experimental studies of the glow discharge characteristics, input power distribution, and glow-to-arc transition phenomena are described. The high- pressure continuous glow was successfully scaled experimentally to a 10 cm square aperture. The excitation concept looks attractive for high-power laser devices.
