Laser performance measurements can be accomplished through a number of techniques and give laser users more relevant, time-based data that portrays trends in laser operation rather than single data points. However, applying this data may seem unclear to some laser users, and raise questions such as how often data should be collected, which measurements should be tracked, and what should be done with it. This article discusses the importance of specific laser performance measurements for many types of applications. Download the full paper for an overview of 5 situations where laser performance measurements are necessary.
