Emission characteristics of a laser-plasma source (LPS) utilizing a YA
G:Nd laser with pulse energy of 0.3 J have been investigated in a rang
e of photon energies from 100 to 500 eV using a spectrometer construct
ed on a base of multilayer X-ray mirrors. The spectral distribution of
the number of photons emitted from a tungsten target under the laser
pulse action has been measured. Line spectra of multicharge ions were
observed in experiments with graphite and beryllium targets.
