Abstract

The results of the study of laser plasma generated by nanosecond laser radiation with controlled spatial coherence incident on various targets containing gadolinium are presented. X-ray radiation of such plasma is studied using an X-ray diagnostic system developed and fabricated by the authors. Metal gadolinium, gadolinium oxide, gadolinium and aluminum alloy, and aluminum were used as targets. The electron temperature of generated plasma and the efficiency of laser-to-X-ray radiation conversion are estimated; the emitting region sizes are determined. Particular attention is paid to the study of laser plasma spectra in the X-ray region near the wavelength of 6.7 nm.
