Resolving damage ambiguity and laser-induced damage threshold (LIDT) complications

June 1, 2019
The ISO 21254 LIDT specification itself is a broad guideline; further refinement helps to best correlate LIDT specifications to real performance.
FIGURE 1. Different root causes of damage create various morphologies of damage, and identifying these morphologies is important for coating and process development; understanding these phenomena is imperative, as overspecifying will drive cost and the resultant damage will degrade laser system performance.

Overspecifying optics for LIDT can unnecessarily increase costs; understanding the statistics behind LIDT will help avoid this problem.
