LIDT – Laser Induced Damage Threshold

The LIDT station is used for determining the laser induced damage threshold (LIDT) of optical components down to the femtosecond regime. The damages are verified offline by Normaski microscopy and the setup can be situated in high vacuum as all the components are optimized for low outgassing.

Features and benefits

Ultrashort pulses in vacuum
Higher accuracy of results in the femtosecond and picosecond regime with respect to real operating conditions

High repetition rate
Allows testing of the effects of ageing and long-term stress

Already tested and in use in ELI Beamlines
The system has been used for internal research extensively and provides comparative results
