German company develops green laser for use in mini projectors
eagleyard managed to produce a prototype of their green laser in cooperation with the Ferdinand Braun Institut für Höchstfrequenztechnik (institute for high-frequency engineering), which is based in Berlin as well. Apart from being directly modulated, the laser is said to be relatively small, precise (line width: 20 picometers), longlasting and economical.
As far as current chip technology is concerned, the institute said using the laser in mobile projectors is not a problem anymore. However, the production of a mini beamer, which is able to fit i.e. in a cell phone, still seems to be a challenge since the hardware will be subject to damage by heat, coldness and abrasion.
Directly competing with New York-based Corning, eagleyard wants to commercialize their technology in cell phones as early as 2009. Hardware prices are expected to be between $800 and $1,600. The mini projectors will not be manufactured in Germany but either in Japan, Korea or the USA.
