ELECTRONICS: The new generation of mini laser bars from OSRAM Opto Semiconductors offers exceptional brilliance in the wavelength range from 910 to 1,020 nm. They are cost-effective, durable and can be easily adapted to meet the requirements of different applications thanks to their small size. In contrast to conventional fiber-coupled diode laser systems, the new bar structures allow more cost-effective beam-forming concepts to be used for fiber coupling. The associated reduction in system costs is a major factor in making diode laser systems more attractive for direct material processing - particularly in comparison with alternative laser solutions. Mini laser bars are available in various application-specific product families, with fill factors of 10 to 20 percent and typical efficiencies of up to 65 percent. In addition to pumping fiber lasers, the laser bars are also used for direct micro-material processing, such as marking and micro-welding.
In a line of ultra-futuristic projects, DARPA is developing a brain microchip that will help heal the bodies and minds of soldiers. A final product is far off, but preliminary chips are already being tested.
