Results of fs laser-produced plasma diagnostics, which were provided using Focusing Spectrometer with Spatial Resolution having as an x-ray detector Princeton x-ray CD or Hamamatsu x-ray MCP, are presented. A portable, high-luminosity spherically bent crystal spectrometers were designed for the purposes of measuring very low emissivity x-ray spectra of different targets, heated by fs laser radiation, with simultaneously high spectral and space resolution. Large open aperture mica spherically bent crystals are used as dispersive elements of spectrometers. High tunability allowed to receive high-resolved spectra of clusters, heated by 35 fs Ti:Sa laser pulses with energy only 15 mJ in spectral ranges: 15-17 angstrom - for H- and He-like ions of Oxygen, 5-5.7 angstrom for Ne-like ions spectra of Kr, 3.0- 3.4 and 3.7-4.4 angstrom for H- and He-like spectra of Ar without any realignment of x-ray CCD spectrometer using one set up. Using another alignment ste up of spectrometer with x-ray MCP has been received spectra of solid targets, heated by 60 fs Ti:Sa laser pulses in spectral ranges: 15.2-17.5 angstrom near resonance lines of He-like ion of fluorine, 7.6-8.75 angstrom for spectra between He(alpha ) and K(alpha ) lines of Al and near Rydberg lines of Ne-like Cu, 3.04 - 3.5 angstrom for spectra around K(alpha ) lines of Ca, 1.38-1.59 angstrom for spectra around K(alpha ) lines of Cu. Some results of plasma diagnostics for both cases of clusters and solid targets, heated by fs laser radiation are presented and discussed.
