Pulser/sustainer electric-discharge in supersonic gas flow
Abstract
The paper deals with the pulser/sustainer electric-discharge concept described by Reilly (1972) which, by uncoupling electron density from electron temperature, permits production of stable uniform electric laser discharges at higher pressures and in larger volumes than those stabilized by surface effects. Results of an experimental investigation of transverse pulser-sustainer discharges in a supersonic nitrogen flow at a total pressure of 2 atm abs are discussed. The effectiveness of such discharges for lasers requiring a low temperature (approximately 80 K) in the discharge zone is pointed out.
