Requirements and test capabilities for the damage threshold of optical surfaces in the ELI-Beamlines facility

摘要

The ELI-beamlines project is expected to reach state of the art parameters in its laser systems. The Laser Induced Damage Threshold of the corresponding optical systems will have to sustain the expected fluences and repetition rates. The LIDT requirements for the ultrafast pulse compressors, vacuum transport mirrors and high average power optics are presented together with the current and planned capabilities for LIDT testing with a 25 TW laser system at 800 and 1060nm.
