我们报告成功的补偿与高能量110 mJ和高平均功率飞秒激光系统的11瓦与真空压缩机光栅操作的热致激光束失真。为了提高基于激光的光源亮度，需要开发具有更高能量和更高平均功率的激光系统。管理真空光学元件上的高热负载是实施这种方法的关键问题。据我们所知，这是第一次，这种热致失真的真空压缩机光栅的特点和补偿。
We report successful compensation of the thermally induced laser beam distortion associated with high energy 110 mJ and high average power femtosecond laser system of 11 Watts operated with vacuum compressor gratings. To enhance laser-based light source brightness requires development of laser systems with higher energy and higher average power. Managing the high thermal loading on vacuum optical components is a key issue in the implementation of this approach. To our knowledge this is the first time that such thermal induced distortions on the vacuum compressor gratings are characterized and compensated.
