    In 1990´s laser technology increased its volume in papermaking industry. Advantages of laser technology in these branches are flexibility, high speed, contact-free processing and possibilities of multifunctional applications. Anyhow, use of laser technology in papermaking has a minor role, mainly because of shortage of basic research results. Previous laser cuttin...

    The innovative water-jet-guided laser technology invented by Synova a few years ago has revolutionized laser microprocessing. With a water jet to guide a laser beam by total internal reflection at the water/air interface, this new technology cannot be confused with a conventional dry laser. In dry laser cutting, the working ...

    Presented at ICALEO 2006

    Individual devices have been saw-cut ("singulated") from wafers since the invention of the integrated circuit. As circuits get smaller and wafers get thinner, however, the limitations of mechanical processes begin to interfere with productivity. Saws tend to chip thin wafers. Newer, more porous "low-k" dielectrics also are prone to chipping when mechanically cut.

    High Power CW fiber laser technology has been developing rapidly and is finding many applications in the industrial sector for metal cutting, welding, heat treatment and more. Recently high average power mode-locked fiber lasers with picosecond pulse lengths and very high repetition rates have begun to appear on the market. Unlike their CW cousins, these lasers pack their energy into pulses that are so short that there ...
