Description

Krypton fluoride (KrF) laser is an efficient ultra-violet (UV) gas laser and can be scaled up to reactor scale direct-drive IFE driver. At the AIST, a prototype rep-rated electron-beam (e-beam) pumped KrF laser/amplifier is being developed to establish technology for rep-rated durable driver, and near term goals, >20 J /pulse at 1 Hz, 104 shot life time, are being reached. To investigate the feasibility of fast igniter scheme with UV laser pulses, the Super-ASHURA (12 beams, 3 kJ) KrF laser has been modified and a focused intensity of 3 x 1018 W/cm2 has been obtained in the preliminary test operation. Target shooting experiments with focused intensity > 1019 W/cm2 are scheduled in near future. (author)
