Fibers Deliver CO2 Laser Beams for Medical Applications

Facebook X LinkedIn Email
Already capable of delivering tens of watts, a novel optical fiber offers the possibility of minimally invasive surgery using CO2 lasers.

An innovative class of optical fibers was developed several years ago at Massachusetts Institute of Technology in Cambridge, based on 1998 work with photonic bandgap reflectors, a new type of dielectric mirror that can reflect light and that displays extremely low losses.1 Unlike other dielectric mirrors, which reflect light only for a very narrow angle of incidence at a specific wavelength, photonic bandgap reflectors are capable of very high reflectance for any angle of incidence and for a large band of wavelengths. This is of particular interest for the fiber beam delivery of...Read full article
