Myths about Laser Damage #1

Damage Threshold of Laser Optic is Limited by Thin Film.

That is a common myth, which is not necessarily true.

Optical elements consist of multiple hidden layers. Thin film is just one of them. Laser-Indued Damage Threshold (LIDT) is an aggregate feature of the optical element and can be limited by various factors such as: sub-surface defects, polishing (Beilby) layer, nodular defects, airborne particles & organics or combination of these issues.

When the element is exposed to intense laser irradiation, each of its layers can lead to failure due to different physical mechanisms (failure modes).
Thus high LIDT optics are usually the result of the optimized development of substrate, interface, coating process, and even the surrounding working environment.
