A petawatt facility fully based on noncollinear optical parametric chirped pulse amplification (NOPCPA) technology, Vulcan OPPEL (Vulcan OPCPA PEtawatt Laser), is presented. This system will be coupled with the existing hybrid-CPA/OPCPA VULCAN laser system (500 J, 500 fs beamline; 250 J, ns regime beamline) based on Nd:glass amplification. Its pulse duration (20 times shorter) combined with the system design will allow the auxiliary beamline and its secondary sources to be used as probe beams for longer pulses and their interactions with targets. The newly designed system will be mainly dedicated to electron beam generation, but could also be used to perform a variety of particle acceleration and optical radiation detection experimental campaigns. In this communication, we present the entire beamline design discussing the technology choices and the design supported by extensive simulations for each system section. Finally, we present experimental results and details of our commissioned NOPCPA picosecond front end, delivering 1.5 mJ, ~180 nm (1/e2) of bandwidth compressed to sub-15 fs.

完全基于 LBO 的超宽带全 OPCPA 拍瓦设施

介绍了一种完全基于非共线光学参量啁啾脉冲放大 (NOPCPA) 技术的拍瓦设备，即 Vulcan OPPEL (Vulcan OPCPA PEtawatt Laser)。该系统将与基于 Nd：玻璃放大的现有混合 CPA/OPCPA VULCAN 激光系统（500 J，500 fs 光束线；250 J，ns 光束线）相结合。其脉冲持续时间（缩短 20 倍）与系统设计相结合，将允许辅助光束线及其辅助源用作更长脉冲及其与目标相互作用的探测光束。新设计的系统将主要用于电子束的产生，但也可用于执行各种粒子加速和光辐射检测实验活动。在这次交流中，我们展示了整个光束线设计，讨论了每个系统部分的广泛模拟支持的技术选择和设计。最后，我们展示了我们委托的 NOPCPA 皮秒前端的实验结果和详细信息，提供 1.5 mJ，~180 nm（1/e2) 的带宽压缩到低于 15 fs。
