Holmium-doped silica fiber laser generates 83 W in high-quality beam.

Breck Hitz

Lasers emitting in the two-micron spectral region have important applications in medicine, spectroscopy and military countermeasures. Traditionally, these applications have relied on holmium-doped crystalline YAG or YLF lasers, but these require cryogenic cooling or complex pumping schemes that limit their usefulness. Fiber lasers are a potential alternative, because robust fiber lasers with kilowatt-level outputs at slightly shorter wavelengths (i.e., 1 to 1.5 μm) have proven very versatile in numerous applications. Until now, however, practical considerations have limited...Read full article

    nano
    An SI prefix meaning one billionth (10-9). Nano can also be used to indicate the study of atoms, molecules and other structures and particles on the nanometer scale. Nano-optics (also referred to as nanophotonics), for example, is the study of how light and light-matter interactions behave on the nanometer scale. See nanophotonics.
    photonics
    The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
