Thermal Laser Induced Damage in Optical Coatings Due To An Incident Pulse Train, an overview

This article is brought to you by: 

Laser Induced Damage Threshold (LIDT) of an optical component de nes the maximum intensity the component can resist before the onset of laser damage and as a result is a critical parameter for any modern laser system, with the LIDT de ning the maximum possible intensity. However laser damage is a multi-faceted and complex problem with multiple theoretical mechanisms depending on pulse duration, optical coating quality and the manufacturing process of the component.

This storage ring free-electron laser from Triangle University Nuclear Laboratory enabled sub-170 nanometer lasing with LZH optics (Triangle University Nuclear Laboratory)

New optics permit sub-170nm lasing

Up until now, oscillator free-electron lasers have only reached emission wavelengths down to 176.4nm
