WebLaser beam profiling provides the tools to characterize the laser and know precisely what the beam is doing at the point of the work and if the optics are having the desired effect. Lasers and laser applications come in many varieties, varying in power density, wavelength, depth-of-focus, beam size, pulse duration and myriad other parameters. WebThe beam profile indicates nuisance high-order spatial modes in a laser cavity as well as hot spots in the beam. Beam astigmatism: The beam is astigmatic when the vertical and …
