BeamSquared® - Measurement Long Rayleigh Range Lasers With Small Focal Spot

The development of remote material processing techniques requires increasing the accuracy of the process to
permit creating smaller features. Laser systems, used for various industrial applications like material processing and micromachining, require small focal spots and at the same time, greater focal lengths. To achieve that, lasers systems combining larger beams, and lower M2, combined with longer focal length lenses are used. This results in smaller focal spots at longer distances from the laser and Rayleigh length, up to 20 meters. To learn more, download the available application note.
