Abstract
The Project of petawatt excimer laser was started at Lebedev Physical Institute (LPI) in collaboration with High-Current Electronics Institute (HCEI). It utilizes Ti:Sa front-end to generate 1mJ, 50 fs pulses, frequency conversion into 2ω or 3ω and direct amplification of short pulses in a chain of excimer amplifiers with e-beam or photochemical pumping. Multi-terawatt output in 20-J, subpicosecond pulses at KrF (λ = 248 nm) is projected being combined with 4-kJ, nanosecond pulses. Petawatt femtosecond pulses at Kr2F (400 nm) might be expected, if transient absorption could be reduced in e-beam-pumped gain medium. For photochemically-pumped XeF amplifiers (480 nm) multi-petawatt level is attainable with a high temporal contrast.
