Laser plasma productions and laser diagnostics for pulsed ion sources

Recent laser assisted works for pulsed ion beam drivers are described. They are divided into two parts as follows. The first one is plasma production by laser light. The second item is the diagnostic of laser produced plasma for pulsed ion diode by laser interferometer. An electron beam pumped excimer laser is operated for the plasma production. Lithium surfaces are directly irradiated by this laser. A resonant interferometer with a dye laser pumped by a nitrogen laser is used to diagnose the lithium plasma. Applicability of this diagnostics for lithium ion diodes is discussed.
