Is efficiency of gain generation in Li III 13.5-nm laser with0.25-Μm subpicosecond pulses the same as with 1 Μm?

摘要

The main goal of this paper is to present experimental results onncomparison of lasing efficiency for Li III 13.5 nm (2-1 transition) linenin LiF microcapillary plasmas using 0.25 and 1 Μm subpicosecondnpumping lasers. A formula for soft X-ray laser efficiency calculation isnpresented and used for such comparisons. The results for dischargencreated preplasma in L=4 mm and L=14 mm microcapillaries are alsonpresented and compared with the results for laser creatednpreplasma
