    "Fibers, Fiber Fabrication and Fiber Lasers"


    Optical fiber-based light sources are a compact, robust and efficient means of converting light from inexpensive laser diodes into bright diffraction-limited beams. Today the lasers span a range of powers, pulse energies and applications, from milliwatt picojoule amplifiers in telecommunication systems to multiwatt millijoule lasers in science and medicine to multikilowatt continuous wave lasers in automobile factories. As part of its investments in fiber lasers, Lawrence Livermore National Laboratory has recently commissioned a facility for fabricating conventional and photonic crystal fibers. This talk will describe research toward building fibers able to generate and transport high pulse energies at high average powers and will discuss fiber’s role in several of LLNL’s current programs, including the National Ignition Facility.

    Speaker Bio(s): 

    Messerly received his bachelor’s degree in physics in 1981 from the University of Dayton and his Ph.D. in optical sciences in 1987 from the University of Arizona. He spent 10 years designing and developing optical fibers for gyroscopes and other sensors at the 3M Co., six years developing telecommunications components at Ciena Corp. and the past 10 years helping to build the Optical Fiber Group at Lawrence Livermore National Laboratory.
