Abstract
The possibility of a gas-dynamic laser with electrical excitation of a thermally ionized gas is studied in detail. The conditions for initiating a spatially uniform discharge in a supersonic flow without the use of external preionizers are discussed. It is shown that energy transfer from the electrons to the vibrational degrees of freedom of molecules is highly efficient. The efficiency of lasers using this effect is three times that of ordinary gas-dynamic lasers.
