Beam Diagnostics: Meeting the Need for High Quality

Facebook X LinkedIn Email
Whether the application is scientific, commercial, industrial or medical, beam diagnostics has become an integral tool for users and manufacturers of lasers and laser-based systems. There is an increasing need to achieve, monitor and maintain higher quality beam characteristics to meet the demands of more sophisticated laser designs and tighter laser process tolerances.

Coherent, Inc.

For any discussion of laser beam diagnostics, it is first necessary to define some terms that characterize beam properties. Broad definitions can include measurements of laser energy or power, spatial intensity, propagation, temporal characteristics and spectral analysis. This article will address measurement of the spatial intensity distribution and propagation characteristics of laser beams. Spatial intensity distribution (commonly called the beam profile) is the measurement of the spatial distribution of power or energy perpendicular to the beam propagation path. It can provide such...Read full article
