    Current Challenges to Laser Cutting Application (Invited Paper)
    Authors:
    Takeji Arai, Chuo University ; Tokyo Japan
    Presented at PICALO 2008

    The laser cutting application is used widely in the world industrial field. Especially in Japan, the ratios that the application of the laser cutting occupies exceed 90% in the whole. Currently, the laser cutting technology for sheet metal cutting was developed instead of punching. Although it becomes the main technology, this technology is still in a stage of the middle of development and the technology is still improved rapidly.
    For the new challenges are always necessary for mature technology. In industry, nowadays, more high-speed cutting and accurat...

    The use of lasers as cutting tools is well established in industry for processing of steels thanks to their great general advantages compared to traditional methods. However, there are materials difficult to be cut by standard laser cutting heads such as some aluminum alloys and ceramics. In this work...

    Presented at PICALO 2008

    Laser Oxygen Thick Section Cutting (LOTSC), a cutting process which utilises the full performance of a supersonic oxygen gas jet for cutting (typically) 30-60 mm mild steel plate, has previously been examined primarily using the CO2 laser. This paper looks at some of the con...

    Presented at PICALO 2008

    The application of lasers in the microelectronics sector has grown steadily over the past 10 years as DPSS lasers have increased power output and high levels of reliability. The readiness of such systems to operate at various output wavelengths such as 355nm has further enabled a greater range of processing operations for Si based microsystems. Recent advances in Yb doped fiber lasers with ...

    Presented at PICALO 2008

    A multiple laser system consisting of CO2 line-shaped and Nd-YAG pulsed lasers was applied to cleave a soda-lime glass substrate in this study. Due to a high absorption of the Nd-YAG laser at a high temperature state of the soda-lime glass preheated by the CO2 line-shaped laser to generate a mixture fracture mode on the glass substrate, the stress distribution on the glass substrate...
