Abstract
The feasibility of creating laser excitation in a diffusion cooled annular coaxial geometry CO2 laser by a longitudinal DC electrical discharge stabilized with a rotating transverse magnetic field has been demonstrated. The uniformity of the electrical discharge in the annular cross section could be enhanced considerably with the application of the magnetic field. A peak laser small-signal gain of 0.3 m-1 was obtained. This scheme could be utilized to construct a compact high-power diffusion cooled CO2 laser system
