High power lasers can become damaged at the most inconvenient times. In order to analyze the specific damage characteristics of high power laser optics, it is important to understand the Laser Induced Damage Threshold (LIDT). LIDT is an advanced analytical threshold determination method that can reveal important damage diagnostics, and its testing provides a lower-cost option for coating development. This white paper details the different test types of LIDT, how to measure the optical thresholds, how to identify defects within high power lasers, and more.
