Paper Abstract

Antireflective thin film coated by TeflonTM AF 2400 amorphous fluoropolymer to improve the pumping efficiency of disk amplifier used for laser fusion is presented. Improvement of pumping efficiency of about 8% can be attained by TeflonTM AF 2400 coating to the outer surface of Xe flashlamps and the shield glasses set up between Xe flashlamps and disk glasses. Flashlamp irradiation test to the Teflon thin film coated on flashlamp wall was carried out. Flashlamp-induced damage for 100 irradiations at about 15.4 J/cm2 was not observed.
