Fundamentals of Beam Profiling

Learn how to measure your laser beam in this video that describes the basics of laser beam profiling. Find out which different shapes of "beam profile" or spatial energy distribution are required for different laser applications, such as welding and cutting. Check out the impact that laser beam diameter has on laser power density. The video gives an overview of the most critical types of laser measurements. It also includes a brief introduction to the tools needed to measure a laser beam, such as BeamMaker, a feature in the Ophir BeamGage software, that let's you learn more about your laser beam and practice beam measurement.

why there is 250 multiplied in power density formula?
