光学参数啁啾脉冲放大（OPCPA） [Dubietis等人，光学学报，88,437(1992)]是一种很有前途的方法来产生超强脉冲(bbb10 （23) W/cm(2)）。欧米茄EP激光系统的升级技术正在开发中，其目标是用两条欧米茄EP光束线泵浦光参量放大器线（EP OPAL）。由此产生的超强脉冲（1.5 kJ, 20 fs, 1024 W/cm(2)）将与其他两条光束线产生的皮秒和纳秒脉冲一起使用。一个由多太瓦（MTW）激光器泵浦的中等规模OPAL正在建造中，可以产生7.5 j， 15 fs的脉冲，并演示适合升级的可扩展技术。MTW OPAL将与MTW激光器（50 J， 1到100 ps）共享一个目标区域，从而实现多种联合射击配置。本文介绍了MTW OPAL系统的现状，以及该类超强脉冲全opcpa激光系统所需的技术发展。
Optical parametric chirped-pulse amplification (OPCPA) [Dubietis et al., Opt. Commun. 88, 437 (1992)] implemented by multikilojoule Nd:glass pump lasers is a promising approach to produce ultraintense pulses (>10(23) W/cm(2)). Technologies are being developed to upgrade the OMEGA EP Laser System with the goal to pump an optical parametric amplifier line (EP OPAL) with two of the OMEGA EP beamlines. The resulting ultraintense pulses (1.5 kJ, 20 fs, 1024 W/cm(2)) would be used jointly with picosecond and nanosecond pulses produced by the other two beamlines. A midscale OPAL pumped by the Multi-Terawatt (MTW) laser is being constructed to produce 7.5-J, 15-fs pulses and demonstrate scalable technologies suitable for the upgrade. MTW OPAL will share a target area with the MTW laser (50 J, 1 to 100 ps), enabling several joint-shot configurations. We report on the status of the MTW OPAL system, and the technology development required for this class of all-OPCPA laser system for ultraintense pulses.
