Deformable Mirror Corrects Its Own Laser Beam Errors

The high power needed to cut or weld using a laser beam creates its own problem: the beam’s energy deforms the mirrors that focus it. When that happens, the beam expands and loses intensity. A new type of mirror is being presented at the Optatec trade fair in Frankfurt next week - it can deform itself to correct deformation the laser beams it controls.Lasers are used in manufacturing to cut materials or weld components together. Laser light is focused to a point using various lenses and mirrors obviously, the smaller the focal point and the higher the energy, the more accurately operators can work with the laser. read more
