Lasers are made of physical matter. Therefore, the natural degradation of their materials can cause variability in performance. Aging optics often cause slow changes in laser behavior and, when left unchecked, these changes can lead to loss of process efficiency. An unclean process environment can quickly change a laser’s behavior through thermal lensing, which is caused by debris collected on laser optics.
In this webinar, produced by Photonics Media, John McCauley discusses how these variabilities are managed, what aspects of a laser’s performance should be analyzed, and what tools are available to perform this analysis.
