Short abstract of the presentation:
Laser-Induced Damage Testing is a vital technique for assessing the  
resilience and operational limits of optical materials, coatings, and  
components under high-power laser exposure. This testing establishes  
the Laser-Induced Damage Threshold (LIDT), representing the maximum  
laser fluence or energy density a material can withstand before  
irreversible damage occurs. LIDT testing is crucial for optimizing the  
performance and safety of high-power laser systems used in diverse  
applications, including telecommunications, medical lasers, industrial  
machining, and military defense systems. In addition since it entails  
studies of ultrafast energy deposition the topic is very important for  
materials science, thermal physics, modeling and simulation and  
surface and interface science in general.
The procedure involves subjecting optical samples to laser pulses to  
ultrashort pulses (in the picosecond to femtosecond regime), across  
various wavelengths and pulse durations. Damage mechanisms may include  
melting, cracking, or ablation, and are typically identified through  
precision imaging and more advanced detection techniques. In this  
seminar I would talk about the topic and present the capability of the  
advanced multimodal prototype LIDT station that we are developing at  
ELI-ALPS [1].
