Abstract
A sample of pure bulk tungsten was studied by laser
induced breakdown spectroscopy (LIBS) method with the aim
to find out a set of W analytic lines allowing a reliable
determination of main parameters of the laser-produced
plasma. The background pressure as well as the recording
direction of spectra were close with those occurring in
fusion reactors. Varying the delay time between the laser
pulse and the data acquisition time-gate, time-resolved
LIBS spectra were recorded at two different laser
wavelengths. On the basis of spectral lines with
negligible overlapping and self-absorption, the
laser-induced plasma temperature as a function of time
has been found.
