New Laser Technologies Displacing Old

Facebook X LinkedIn Email
High-power fiber and diode lasers are reshaping the materials processing sector, while powerful blue lasers are finding their niche in select welding applications.

For some CO2 laser applications, the end is at hand, with fiber lasers having almost totally replaced the older technology. Another shift currently brewing is due to the arrival of high-power diode lasers, which are impacting materials processing and driving down the cost of ultrafast lasers through the advent of direct diode pumping. Replacing CO2 lasers with fiber lasers increases metal cutting speeds 2 to 5×. Courtesy of Bystronic. In these transitions, the lasers that win out typically cost less, are easier to operate and are more robust. They also may offer other...Read full article

    system on chip
    Abbreviated SoC. A single chip containing all the electronic circuits required for a complete, working product. SoCs are similar to microcontroller technology but provide additional components. A SoC for a smartphone can include graphics, audio, video and camera processing in addition to all the microcontroller circuit. By compacting more electronic circuits onto one chip, miniaturizing and creating power efficient technology becomes feasible.
