Efficient method of gas laser pumping by an electron beam in the SIGE-1 experimental setup

Lasers, sources of coherent UV and vacuum UV radiation, plasmachemical reactors, reactors for cleaning fouled gases, etc., can be classified as devices the working medium of which is plasma formed as a result of the interaction of a high-current relativistic electronic beam with gas. Efficiency of such devices which are united under the common name “systems of injection gas electronics” (SIGE) depends mainly on the efficiency of energy transfer from a beam to gas (η g = W g / W b ) and that of the transform of the energy transferred to gas into the energy of the ultimate product W in (η in = W in / W g ). As a special case of SIGE, an experimental bench laser is considered. The new efficient method of pumping is supposed to be implemented on this laser to optimize the energy contribution η g and useful output η in .
