All rights reserved 2 WLT-Conference „Lasers in Manufacturing” A personal Welcome to Munich! Thank you for coming to Munich and participating in LiM 2009! The International Conference on Lasers in Manufacturing LiM 2009 has been well established as one of the most important meetings in the field of laser based material processing. One of the main reasons for the continuous success of LiM might be the location. Germany and its laser industry as well as a very powerful scientific landscape with large laser and photonics institutes has been one of the pacemakers in this field over the past decades. Of course, Munich with its nice beergardens also offers many other opportunities in summertime. The German Scientific Laser Society (WLT) as the organizer of LiM, wants to stimulate the exchange of knowledge and ideas with international researchers in this exciting field. Therefore, we are very pleased that again many international participants contribute either by very interesting presentations or just by visiting this event. On behalf of the conference chairs we express our special welcome to those who travelled long distances, despite the difficult economic situation all over the world. This gives us confidence that research in new production technologies will still be a very important factor in the preparation of industry for the turnaround. Lasers in Manufacturing is both: an old and a fresh topic. Old in this sense does not mean that it has passed its heights already. It is established more and more not only in huge global companies but gradually also in small and medium sized companies. The evidence that this field is still as fresh as in the beginning is brought to you by LiM 2009. New laser concepts with extraordinary beam qualities and output powers orders of magnitude higher than a few years ago, open the horizon for many applications people have thought about in the past as science fiction. Today it is reality. Finally, we wish you a very successful week at LiM 2009, many new impressions also in combination with the exhibition LASER – World of Photonics, and – very important – a lot of new friends!

Doctoral Dissertations. 1353. https://opencommons.uconn.edu/dissertations/1353 Nonlinear Optical Processes for Spectral Broadening and Short Pulse Generation Hongyu Hu, PhD University of Connecticut, 2017 The dramatic progress in optical communication is attributed to the development of wavelength- division multiplexing and time-division multiplexing technologies, which employ broadband light source and ultrashort optical pulses respectively to carry signals in optical fibers. Supercontinuum generation is the spectral broadening of narrow-band incident pulses by the propagation through optical waveguides made of nonlinear materials. In this PhD dissertation, I show the design of a tapered lead-silicate optical fiber for supercontinuum generation. The physical mechanisms of optical pulse evolution are explained, which involve various nonlinear optical effects including self-phase and cross-phase modulation, stimulated Raman scattering, four-wave mixing, modulation instability and optical soliton dynamics. I have also proposed planar waveguides with longitudinally varying structure to manage chromatic dispersion, and numerically simulated the generation of (1) broadband and (2) flat octave-spanning supercontinuum output. The coherence property and noise sensitivity of supercontinuum are also investigated in this dissertation, which depend strongly on pumping conditions. A hybrid mode- locked erbium-doped fiber ring laser, which combines rational harmonic active mode-locking technique and graphene saturable absorber, has been designed and experimentally demonstrated to produce optical pulse train.

  • The Current and Future State-Of-The-Art Glass Optics for Space-Based Astronomical Observatories
    The Current and Future State-of-the-art Glass Optics for Space-based Astronomical Observatories Abstract Recent technology advancements show significant promise in the ability to reduce the cost, schedule and risk associated with producing segmented Primary Mirrors (PMs) as well as monolithic optics larger than Hubble Space Telescope (HST) scale to the surface figure and smoothness required of current and future astronomical systems. This paper describes the present state-of-the art technology for glass mirrors at ITT and a path to next generation technology for use in a wide range of applications. In-process development activities will be discussed as well as the areas in which future investments can further enhance glass PM technologies. Active, passive, monolithic, and segmented mirror technologies will be discussed along with some basic descriptions of the different ways by which light-weighted glass mirror blanks are fabricated. There will be an emphasis on Corning’s Ultra Low Expansion (ULE®) and borosilicate optics, with some discussion of glass ceramics and other material substrates. The paper closes with a table that summarizes potential areas of investment that will continue to advance the state of the art for the use of glass and other materials in optical systems.
