Jeff Perkins, Ph.D., of Fiberguide Industries presented his original research on beam control through fiber taper geometry manipulation at the 3rd WSOF (Sigtuna, Sweden) in August. By manipulating the geometry of a fiber taper, it is possible to shape and control the beam output of large core fibers. This has useful applications in diverse industries such as laser welding or cutting, digital projection, or lithography, where beam shape control and uniformity can improve efficiency and/or beam quality. Traditional means of beam shaping using refractive or diffractive optics tend to be costly and usually require labor intensive alignment. As a more cost effective alternative, Fiberguide is able to offer a custom inline, low loss, fiber taper solution.
