Population Inversion Non-Equilibrium Flow Simulation Calculations of the Capabilities of Convection Flow Lasers
Abstract
Fluid mechanics and non-equilibrium state thermal dynamics are brought together to form 'hot gas dynamics'. The test production of high power lasers has quickly developed. The flow movements of working media have important effects on high power laser devices. (1) The convectionary heat diffusion heat dissipation. (2) Flow movements make the working medium constantly replace itself. This makes it possible to maintain the stability of the working medium as well as to continuously replenish the energy source. (3) It is possible to make use of rapid expansion to directly form population inversion. Because of this, the high power lasers which currently exist - gas flow lasers, flow movement and electrical discharge lasers, quasimolecular lasers, chemical lasers, and other similar devices make use of reactive flow gases to act as working media.
