Characteristics of laser produced plasmas and lasers for pulsed ion sources

Preliminary experiments were performed to investigate the fundamental characteristics of the laser produced plasmas and the KrF lasers for the pulsed ion beam production. (1) Lithium target was irradiated by a small e‐beam pumped KrF laser and the exhausted plasmas were measured. (2) A larger KrF laser of the same kind was operated and the output characteristics were observed. (3) The mode patterns of a discharge‐pumped KrF laser was also measured most recently to prepare the future target irradiation to produce ion‐source plasmas.
