摘要：

Flux of X-ray radiation emitted from the Ta plasma, produced by the fundamental (1 omega) and the third harmonic (3 omega) frequencies of the high-power iodine laser PALS, was studied in dependence on the laser focus position. One or two (three) maxima, corresponding to the hard or soft component of the emitted spectrum, can appear, according to the experimental conditions. These dependencies are compared with those published by other authors, and also with our results concerning the highly charged ion generation. At laser intensities above I-L similar to 10(14) W/cm(2) , the participation of non-linear processes in the pre-formed plasma was confirmed.
