Study of Thermodynamic and Optical Characteristics of Active Media for Laser Gas-Plasma Injectors

Results of numerical simulation and experimental study of thermodynamic and optical characteristics of working agents - active media for pulse laser injectors of high enthalpy gas-plasma flows, having a complicated chemical composition, are given. The agents are based on plasma-creating elements of polymeric compounds of a range of temperature T ~ 0,1-10 eV, density ρ ~ 10^-4-10^-1 kg/m³ and quantum energy hv ~ 0,1-10 eV. These characteristics are required to characterize quantitatively all energy transformation phases in laser injection sections - the flow generation, heating and shock-wave acceleration in strong fields of coherent radiation.
