About This Webinar
Lasers used for material processing face two general challenges over the course of their lives. First, these lasers operate at relatively higher power levels compared to lasers used in other applications. Second, the environments in which these lasers operate are usually harsh. These two challenges can cause the laser's performance to drift over time, causing adverse effects on their processes. In this session, McCauley discusses first, which laser performance characteristics are meaningful to measure, second when, and at what frequency, these characteristics should be measured, and third and most importantly, how changes in these characteristics relate to the process.
