| 1 | MTW-OPAL:a technology development platform for ultra-intense optical parametric chirped-pulse amplification systems显示文摘Optical parametric chirped-pulse amplification implemented using multikilojoule Nd:glass pump lasers is a promising approach for producing ultra-intense pulses(>10^(23)W/cm^(2)).We report on the MTW-OPAL Laser System,an optical parametric amplifier line(OPAL)pumped by the Nd:doped portion of the multi-terawatt(MTW)laser.This midscale prototype was designed to produce 0.5-PW pulses with technologies scalable to tens of petawatts.Technology choices made for MTW-OPAL were guided by the longer-term goal of two full-scale OPALs pumped by the OMEGA EP to produce 2×25-PW beams that would be co-located with kilojoule-nanosecond ultraviolet beams.Several MTWOPAL campaigns that have been completed since“first light”in March 2020 show that the laser design is fundamentally sound,and optimization continues as we prepare for“first-focus”campaigns later this year. | J.Bromage S.-W.Bahk M.Bedzyk I.A.Begishev S.Bucht C.Dorrer C.Feng C.Jeon C.Mileham R.G.Roides K.Shaughnessy M.J.ShoupⅢ M.Spilatro B.Webb D.Weiner J.D.Zuegel | 2021 | High Power Laser Science and Engineering2021，9，4： | 1 |
