Ne-Like Ion X-ray Laser Experiments in Plasmas Produced by 0.53- mu M and 0.35- mu M Laser Light

摘要

Recent Ne-like ion x-ray laser experiments carried out at the Centre d'Etudes de Limeil-Valenton (CEL-V) with both 0.53- mu m and 0.35- mu m laser light will be described. This paper will concentrate primarily on the observation of amplification in Ne-like Sr (Z = 38) in plasmas produced by 0.53- mu m laser light. Small signal gains of 4.4 cm/sup /minus/1/ and 4.0 cm/sup /minus/1/ have been measured for the Ne-like Sr J = 2--1 transitions at 164.1 and 166.5 /angstrom/, respectively. In addition, the effects of pumping the Ne-like Se laser with 0.35- mu m light have been investigated. The resulting Se spectra do not differ significantly from those observed with 0.53- mu m light. A brief summary of other experiments carried out at CEL-V will also be given. 18 refs., 5 figs., 1 tab. (ERA citation 14:011561)
