Abstract

We present the design and performance of the Texas Petawatt Laser, which produces a 186 J 167 fs pulse based on the combination of optical parametric chirped pulse amplification (OPCPA) and mixed Nd:glass amplification. OPCPA provides the majority of the gain and is used to broaden and shape the seed spectrum, while amplification in Nd:glass accounts for >99% of the final pulse energy. Compression is achieved with highly efficient multilayer dielectric gratings.

我们介绍了德州拍瓦激光装置的设计与性能，该装置基于光参量啁啾脉冲放大（OPCPA）和混合钕玻璃放大相结合的技术，产生能量为186 J、脉宽为167 fs的脉冲。OPCPA提供了大部分增益，并用于展宽和整形种子光谱，而钕玻璃中的放大过程占最终脉冲能量的99%以上。压缩是通过高效多层介质光栅实现的。
