Abstract: With the help of the transmission grating spectrometer (PTGS), we have obtained the real emission spectra of several elements. The band structures of the soft x-ray spectra from laser produced plasmas are extensively studied as the function of atomic number and laser intensity. Finally, the PTGS space-resolved spectra from the laser heated half-cylindrically grooved target show that this kind of semi-closed geometry is a promising candidate for x-ray laser targets.!13
