However, the semiconductor laser light output will increase with the increase of current, present, many power semiconductor laser drive current up to 70mA, 100mA or 1A level, need to improve
the packaging structure, a new semiconductor laser package design and low heat resistance package structure and technology to improve the thermal characteristics. For example, using a large area
flip-chip structure, selection of good thermal conductivity of silver plastic, metal stents increases the surface area of silicon carrier solder bump directly mounted on the upper heat sink method.
Twelve South has announced PlugBug World ($45), an all-in-one international version of its PlugBug. PlugBug World piggybacks onto a MacBook power adapter, allowing simultaneous charging of a
MacBook and iPad, iPhone, or iPod from the same outlet, adding a separate 2.1-Amp USB port. PlugBug World includes five international snap-on plugs for use in the UK, Europe, Australia, China, and
North America.
For the past two months, the Editors of iLounge have been quietly previewing new iPad, iPhone, iPod, and Mac accessories that are making their first official debuts at the 2013 International CES in
Las Vegas. Even before CES opened, we saw new products from numerous companies, and then hit CES’s floor to explore hundreds of booths and thousands of products. After extended discussions and
debates, our team selected only the very best new products for our awards: full Best of Show Winners offer the rare combination of great design, features, and pricing, while Best of Show Finalists
demonstrate excellence in two of those categories but fall a little short in the third.
Congratulations to all of the winners! In the theoretical analysis, to Moscow, Lebedev Institute of Physics, Nicholas ? Basov of the most outstanding work. In July 1962 meeting of the
International Conference on Solid Devices Research, Massachusetts Institute of Technology Lincoln Laboratory of the two scholars Keye Si (Keyes) and Qwest (Quist) reported the phenomenon of light
emission material gallium arsenide, This caused General Electric Research Laboratory engineer Hall (Hall) the great interest in the train home after he wrote the data. Back home, Hal immediately
developed a plan developed by the semiconductor laser, and with other researchers to work together after several weeks of struggle, the success of their plan.
