Abstract
For high energy chirped pulse amplification laser systems, the laser damage of optical components after the compression stage, in particular diffraction gratings and mirrors for beam transport, remains one of the main limitations to the maximal output energy of lasers. We will provide an overview of historical pulse compression gratings for ultrafast, recent advancements, and challenges going forward.
