A Quantitative Theory of an Electron-Beam-Excited Carbon Monoxide Gas Dynamic Laser: 1. Formulation
Abstract
A new concept for a high power CO gas dynamic laser, coupling a supersonic expansion nozzle and an electron beam preionizer-sustainer discharge system, that promises both the high efficiency of an electrically pumped CO GDL and the high power of a thermally pumped CO GDL. The superiority of the proposed laser to existing CO lasers for atmospheric application is shown. General operational characteristics of a CO laser, and a state of the art review of the various types of continuous-wave CO lasers are given. The principle of anharmonic (V-V) pumping is presented, and the excitation and inversion mechanisms of these CO lasers are described. Finally, a quantitative theory is formulated to describe the new laser, and a frozen flow approximation of the problem is proposed.
