摘要

本文报道了一种采用双晶形变形反射镜和Shack - Hartmann波前传感器的大口径自适应光学系统，用于最先进的千瓦钛蓝宝石激光器的像差校正和光束聚焦改善。我们考虑了向波前传感器提供反馈并获得优化光束聚焦到目标的目标波前的方法。在输出功率为4.2 PW的Ti:蓝宝石激光器中，使用带有可控127通道320 mm口径反射镜的自适应系统，可以获得创纪录的高激光束强度:1.1 × 1023 W cm−2。

Large-aperture adaptive optical system for correcting wavefront distortions of a petawatt Ti : sapphire laser beam

This paper reports a large-aperture adaptive optical system with a bimorph deformable mirror and Shack – Hartmann wavefront sensor for aberration correction and beam focusing improvement in state-of-the-art petawatt Ti : sapphire lasers. We consider methods for providing feedback to the wavefront sensor and obtaining an objective wavefront that optimises beam focusing onto a target. The use of an adaptive system with a controlled 127-channel 320-mm-aperture mirror in a Ti : sapphire laser with an output power of 4.2 PW has made it possible to obtain a record high laser beam intensity: 1.1 × 1023 W cm−2.
