Laser Damage infobase

Background knowledge about laser damage is often necessary for high-power laser optics manufacturers, optics distributors, and high-power laser system engineers. Here You will find useful and easy-to-understand explanations related to the main topics of LIDT terminology.

Happy reading!

What is laser damage?

Learn what is Laser-Induced Damage.
What is Laser-Induced Damage Threshold or LIDT?

Laser Induced Damage Threshold (LIDT) is a physical characteristic of optical component which defines a critical power or peak fluence of laser irradiation causing irreversible changes in materials structure.
Defects in optics and defect driven laser damage

Optical elements used for lasers are imperfect. Even a super polished glass surfaces hide thousands of defects upon and beyond the top layer.
Morphology of laser-induced damage

Typical examples of various laser induced damage morphologies.
Laser irradiation level

Units of laser-induced damage threshold
Effective laser pulse width

The effective pulse width is used to describe laser pulses featuring not rectangular (in example Gaussian or another irregular) shape in time.
