Numerical Analysis for the Power of a Supersonic Flow CO Chemical Laser

Abstract

A numerical analysis is presented with a CO chemical laser, which utilizes the supersonic mixing of the dissociated products of CS₂ diluted in Ar with O₂. It is assumed that the flow is quasi-one-dimensional, and that the nozzle flows undergo instantaneous mixing at the nozzle exits. The constant gain method is applied to estimate the laser power. The present results show that the rate of formation of the CO molecules is scarcely reduced, although the temperature rise in the reacting flow field is suppressed due to the conversion of the chemical energy into the laser energy. It is also shown that about 19.5 KW laser power can be extracted from a supersonic flow CO chemical laser, whose cross sectional area of the flow field is 50 mm ×450 mm.
