CO2 MHD Laser: Analysis, Design and Shock Tunnel Experiments.

Abstract

MHD (magnetohydrodynamic) laser gain exceeding 0.2%/cm has been achieved in the GE/ONR shock tunnel using a mixture of 78% Helium, 18% Argon and 4% CO2 with either 1% Xe or 0.1% Cs added to the basic mixture for seeding. Long relaxation times and non-emitting electrodes required use of some external voltage augmentation to achieve the necessary plasma conditions in the available generator length. The MHD laser analysis, design of a channel based on that analysis, and experimental results to date are discussed. (Modified author abstract)
