RADIALLY CONVERGENT 30-100-MU-S E-BEAM-PUMPED XE AND NE LASERS

The design scheme of a radially convergent 30-, 70-, or 100-mu s e-bea m-pumped laser with 9 or 18 1 excited volume is described. Amplitude, temporal, and spectral characteristics of the laser output, as well as laser thresholds in (Ar-Xe, He-Ar-Xe, He-Ne-Ar, and He-Ne-Ar-H-2) gas mixtures have been investigated. The distribution of the specific dep osited energy over the laser chamber cross section has been calculated by the Monte Carlo method. The small signal gain and unsaturable loss values of the active medium were measured for a Penning plasma Ne las er at lambda = 0.585 mu m.
