Green laser diode from OSRAM Opto Semiconductors is product of the year 2012 awarded by Electronic Products Magazine

Electronic Products Magazine (USA) has nominated the green laser diode from OSRAM Opto Semiconductors their product of the year 2012. Readers of the German magazine “Elektronik” also chose the green laser diode from a total of eleven nominations as one of the three best products of the year 2013 in the Optoelectronics category.

Green laser diodes – a milestone in the development of miniature projectors

The green laser diodes represent a milestone in the development of miniature projectors for mobile devices such as smartphones and cameras. Units for laser shows, point lasers and line lasers will also benefit from this technology. The compact laser diodes have an optical output of 30 and 50 milliwatts and a particularly high beam quality and are direct emitting - the laser light is produced directly in the semiconductor. Compared with existing solutions, there is no longer a need to double the frequency of an infrared laser to produce green light.

The direct emitting green laser diodes have a number of advantages

  • High thermal stability
  • Compact design
  • High-quality beam
  • Rapid modulation speeds

These advantages represent an important step for pocket projectors that will enable anyone to carry their PowerPoint presentations or favorite videos with them and view them at a reasonable size on a wall or projector screen. The compact PL 520 and PL 515 direct emitting green laser diodes with their optical output of 50 mW and 30 mW are ideal for such applications. Designers can now develop and construct usable small projectors for smartphones and cameras, and also projection units for laser shows, point lasers and line lasers.

Osram Opto Semiconductors developes one of the first direct emitting green laser diodes

With the development of one of the first direct emitting green laser diodes Osram Opto Semiconductors has underlined its leading position in lasers based on indium gallium nitride. The green laser is the result of years of intensive development work in Regensburg. It has been developed as part of the MOLAS project sponsored by the German Ministry for Education and Research and involving technologies for ultra-compact and mobile laser projection systems. In 2010, researchers at the company received the Karl-Heinz-Beckurts Award for development work on the green laser.
