| Abstract: | In high power excimer laser system, the shape of output laser beam from whole system is mainly determined by the front end of laser beam, and is closely correlated to the requirement of target physics. The experimental development of the front end laser beam shape control based on a short pulse excimer laser is described. A partial coherence scattering source satisfying requirement of system construction has been developed, and the top hat laser shaping pulse by three pulses stacking has been obtained. Also, analysis on above methods combining experimental results is given |
