Abstract
The radiation emitted from laser-produced plasmas of tungsten, ytterbium, and samarium has been observed at different wavelengths in a range of 30-200 am by means of timeresolved spectroscopic method. A Q-switched ruby laser (1.5 J/pulse, 18 as in FWHM) gave a power density of about 10 10 W/cm2 on the target. The intensity integrated over one pulse is found to be reproducible to ±20% or better over several tens of laser shots on the single target spot. The integrated intensity and FWHM of the VUV radiation are nearly inde pendent of the target materials studied, and their dependence on the angle of incidence of the laser beam is also described.
