The possible use of a laser to produce a plasma with an approximately constant density, a nearly homogeneous temperature profile which varies little with the time, and an approximately planar configuration is studied. Values are found for the properties of the air behind a plane plasma front propagating rapidly opposite the laser radiation due to emission and absorption of radiation in a continuous spectrum. The lower limit for the existence of such supersonic radiation waves is estimated for the case of a neodymium-glass laser. The results of a numerical solution of the radiation-gasdynamic problem are compared with a simple model for the quasisteady stage of the phenomenon, and a qualitative explanation is offered for the behavior of the properties as the flux density and wavelength of the laser radiation heating the plasma are varied. The possibility of experimentally studying this phenomenon is discussed. (AIP)
