About This Webinar
Beam profiling describes the measurement of the spatial distribution of power of a laser beam. Laser users often wonder if they need to profile their lasers but may have nagging doubts as to why. That is understandable, since beam profiling involves a seemingly bewildering array of techniques and specifications. And while beam profiles often involve interesting pictures, it is not always clear how to extract useful results. In this webinar, Derrick Peterman, Ph.D., of Ophir, will outline the standard techniques involved with beam profiling and the key practices that produce reliable beam profiling results.

Peterman will discuss the data obtained from beam profiles and how it is used to make technical decisions. He will cover the two main families of beam profiling instrumentation: sensor arrays and scanning apertures. In addition, he will dive into how to attenuate the beam properly to obtain a reliable profile, an underappreciated aspect of beam profiling. Peterman will conclude with real-world examples where the beam profiles unlocked key insights about the performance of the laser or optical system.

The webinar will close with an open question-and-answer session.
