    Presented at PICALO 2006

    Excimer micromachining tools used to produce micromachined parts are often controlled by manually written numerical control (NC) part programs in RS-274 "G" and "M" codes, or NC-code. The manual creation of the part programs in NC-code is a time-consuming process for users and relies on their exper...

    Micro Joining and Cutting with a Single Mode Fiber Laser
    Authors:
    Mohammed Naeem, GSI Group, Inc.; Rugby Great Britain
    Presented at PICALO 2006

    Since the early developments of laser micro machining, the lamp pumped pulsed Nd: YAG laser has been the source of choice. Single mode fiber lasers have recently emerged as potential alternative sources for laser micro machining. These lasers with diffraction limited beam quality offer many advantages such as small spot size, high power density, enhanced processing speeds, reduced heat affected zone for both cutting and joining applications respectively. In this work, we will provide cutting and welding data achieved with a 100W single mode fiber for a ...

    Optical Surface Profilometry of Low Reflectance Materials – Evaluation as a Laser Processing Diagnostic
    Authors:
    Adam Joyce, Department of Physics; Sydney Australia
    Deb Kane, Macquarie University; Sydney Australia
    Presented at PICALO 2006

    Optical surface profilometry is a technique which has advantages over other profilometry techniques (stylus profilometry, AFM) of being non contact and being able to profile comparatively large areas in a single "z-scan". Thus, it is employed in monitoring surface quality and measuring surface form in high technology manufacturing processes and quality assurance, as well as in research and development contexts. Its application to optical materia...

    Presented at PICALO 2006

    Metallic nanoparticles exhibit fascinating optical properties due to the surface plasmons * the collective oscillation of electron cloud within the particle. Surface plasmon can be at a resonant condition with the driving electromagnetic wave, and its resonant peak is shown to be tunable at various wavelengths of light with the shape a...

    Peter Loosen, Fraunhofer-Institute für Laser Technology; Aachen Germany
    Wolfgang Schulz, Fraunhofer-Institute für Laser Technology; Aachen Germany
    Presented at PICALO 2006

    With the advent of high power diode lasers of lifetimes in excess of 10,000 hours at long term operational power levels in the range of 100W per diode bar, diode pumped concepts moved into their rightful role as next generation sources. The main reason for this trend is the combination of laser efficiencies in the range of 15 to 25% at powers of several kW with t...

    Laser Applications in Additive Manufacturing: Spanning Microns to Meters
    Authors:

    Presented at PICALO 2006

    Lasers are currently being applied in many aspects of conventional material processing including cutting, welding, drilling and machining. In recent years laser have been increasingly applied in the development of additive manufacturing technologies ranging from rapid prototyping to rapid manufacturing. The Laser additive manufacturing (LAM) technologies encompass a wide range of applications on scales that cover six orders of magnitude from microns to meters. LAM technologies are processes that use computer contr...

    Presented at PICALO 2006

    Conventional lithography by laser mask projection has several drawbacks in terms of flexibility and costs which result in its use only for mass production. Small batches can be processed more easily and cost effectively by using direct laser writing. Laser direct ablation of resists and direct laser photopolymerisation can be used to ...

  • PICALO 2008 Paper #1005 (Laser Material Processing in the Aero Engine Industry. Established, Cutting-Edge and Emerging Applications.)

    Laser Material Processing in the Aero Engine Industry. Established, Cutting-Edge and Emerging Applications.
    Authors:
    Karl-Hermann Richter, MTU Aero Engines; Munich Germany
    Presented at PICALO 2008

    Laser machining processes are widely used in the manufacture and repair of aero engine components. This presentation provides examples of well-established, cut-ting-edge and emerging laser machining processes. A well-established process is laser drilling which has been in use for more than 25 years to produce cooling holes in combustors and particularly in high-pressure turbine (HPT) blades and vanes. To enhance the cooling efficiency a novel laser machining technique has been devel-oped to produce sh...
