    Abstract: A radiation source having a fuel stream generator (110) that generates and directs a fuel stream (102) along a trajectory towards a plasma formation location (104). A pre-pulse laser radiation assembly directs a first beam of laser radiation (100) at the fuel stream at the plasma formation location to generate a modified fuel target (106). A main pulse laser radiation assembly directs a second beam of laser radiation (108) at the modified fuel target at the plasma formation location to generate a radiation generating plasma (117). A collector (122) collects the radiation and directs it along an optical axis (105) of the radiation source. The first beam of laser radiation being directed toward the fuel stream substantially along the optical axis.
