Claim 12:
13. A method for plasma ignition in a laser-pumped plasma light source comprising: directing a focused beam (3) of continuous wave (CW) laser (4) into a gas filled chamber (1), at least part of which is optically transparent, plasma ignition and stationary sustenance of a radiating plasma (2) by focused beam of CW laser, characterized in that
the plasma is ignited by a solid-state laser system (7) with single active element (10), which generates two parallel pulsed laser beams (8), (9) focused into the chamber; one beam (8) of said two pulsed laser beams is generated in a free running mode, and another pulsed laser beam (9) is generated in a Q-switched mode by an installed in an optical cavity Q-switch, overlapping only part (15b) of the cross section of the intracavity laser beam (15).
