High power laser damage & annealing - Justification for ISO Standard Recommendations

This article is brought to you by: 

Values for Laser Induced Damage Thresholds (LIDTs) can vary. Inflated values give a rosy glow to the coater and a redder glow to the end user when their optics damage under seemingly safe conditions. There is much finger pointing within the damage community and there are numerous sources of variance. This situation highlights the importance of following the ISO standards for laser damage testing. 

Understanding the differences in high-power pulsed and CW damage

This article is brought to you by: 

All of us who work with high power lasers have experienced laser damage, usually when we least wanted to. Sometimes just an unexpected flash of light means an optic needs to be replaced, but often the case is far worse where a single coating damage can lead to systemwide failure. Much of our work is certifying optics for pulsed laser systems in order to prevent this kind of catastrophic event.

This whitepaper dicusses in scientific detail the laser damage caused by pulsed and CW high-power systems.
