Inhomogeneity and scatter from inclusions and bubbles in optical components can lead to worse performance, especially in laser optics applications.

Laser induced damage threshold (LIDT) denotes the maximum laser fluence an optical component can withstand with an acceptable amount of risk.

The length of a laser resonator determines the laser’s resonator modes, or the electric field distributions that cause a standing wave in the cavity.

The diameter of a laser highly affects an optic’s laser induced damage (LIDT) as beam diameter directly impacts the probability of laser damage.

Testing laser induced damage threshold (LIDT) is not standardized, so understanding how your optics were tested is critical for predicting performance.

The short pulse durations of ultrafast lasers make them interact with optical components differently, impacting the optic’s laser damage threshold.
