Abstract
The thermodynamic gasdynamic parameters of the active media of subsonic and supersonic open- and closed-cycle electron-beam-controlled lasers (EBCL) are theoretically calculated. The optimal characteristics of the pumping system and of the thermal regimes of the active medium, which permit a considerable improvement of the energy characteristics of the EBCL, are calculated. The investigations make it possible to increase the efficiency and the working-medium pressure of cw electron-beam-controlled lasers and decrease the dimensions of the laser installations.
