Web10 nov. 2024 · How Do Laser Cutters Work. The laser is generated by a laser resonator, which emits a strong light beam reflected by a mirror system to the cutting head. The laser is then focused through a lens within the cutting head and reduced to an incredibly thin, concentrated beam. Then, the beam is directed at the material and can cut the raw stock. WebOptical vortices are studied by creating them in the lab in various ways. They can be generated directly in a laser,[2][3]or a laserbeam can be twisted into vortex using any of several methods, such as computer-generated holograms, spiral-phase delay structures, or birefringent vortices in materials.
