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.
Are you being paid enough? Do you want a better job? According to a recent survey Manpower released just before Engineers Week, employers and engineers don't see eye-to-eye about the state of US engineers' skills and experience.
Two issues have been the bane of the plastics industry for as long as one can remember: The ban on plastic grocery bags and whether the use of bisphenol A (BPA) in plastics such as polycarbonate and PVC is harmful to humans.
One expects to see outlandish apparel at major global fashion events, but New York Fashion Week may have outdone itself, and set a new bar for Paris and Milan, when it put an Ebola jumpsuit in the spotlight.
