Know Your Beam Profile.
Understand Your Setup.
Reliably Optimize Your Laser.

Precise laser beam characterization is essential for the quality and stability of modern laser systems. Alongside laser power and wavelength, the spatial intensity distribution in particular affects focus size, power density, and process quality. A complete beam analysis therefore provides significantly more information than a simple measurement of beam diameter.

With the BeamPro laser beam profilers, TOPAG offers powerful instruments for research, development, and industrial applications. The systems capture the two-dimensional intensity distribution of the laser beam and precisely determine beam size, beam position, focus diameter, divergence, Gaussian fit, beam ellipticity, and other beam parameters according to ISO 11146. This allows laser sources to be reliably characterized, optical systems to be efficiently aligned, and processes to be continuously monitored.

What Users Say About Our BeamPro Cameras

"Over the past years, we have been consistently impressed with the BeamPro beam profilers we’ve purchased, and they performed exceptionally well in our work."
Senior Researcher, ASML
"The BeamPro and MS-ROC Autocorrelator are well equipped to characterize the fs laser for our research lab. The BeamPro provides good quality images and great tracking for beam stability. The MS-ROC has a clear design and is easy to align and measure the pulse width of the beam. The information is saved in convenient formats for further analysis. The STAR software has a clean and customizable interface, yet is packed with features. We appreciate how Femto Easy has implemented our suggestions for improving the software. We look forward to using this equipment for characterizing and monitoring our broad range output OPA and SHG beamlines as we build and use our pump-probe laser system for photoemission orbital cinematography."
