摘要
The present invention relates to an electrically operated discharge, by a method and apparatus for generating optical radiation, in particular EUV radiation or soft x-ray. Plasma 15 is ignited in a gas medium between at least two electrodes (1,2), wherein the gas medium is applied to one or several surface (s) moving in the discharge space and one or several pulsed energy beams at least in part, at least in part, it generated from a liquid material (6) that by evaporation. In the proposed method and apparatus the at least two consecutive pulses within a time interval of each electrical discharge on said surface (s) (9, 18) is applied. By this means, the collecting possible conversion efficiency is increased as compared to using only a single energy pulse in each of the electric discharge. ;
