Paper Abstract

An e-beam pumped Xe-laser is experimentally investigated with additions of molecular gases. For a pump pulse duration from hundreds of nanosecond to 1 μs, the highest laser energies are reached without molecular additions at a comparatively low e-beam current density (~ 10 kW cm-3 atm-1). However, in setups with specific pump powers above 40 kW cm-3 atm-1 and a working mixture pressure limited by strength of the laser chamber, molecular additions result in an increase in the radiation energy and efficiency. In wide-aperture facilities with high pump powers, molecular additions improve the distribution of the radiation power density over the laser-beam cross section.
