Sunnyvale, CA--Scientists at Osram Opto Semiconductors have been honored by the Karl Beckurts Foundation for their work in developing a direct green-emitting semiconductor laser.

Sunnyvale, CA--Scientists at Osram Opto Semiconductors have been honored by the Karl Beckurts Foundation for their work in developing a direct green-emitting semiconductor laser.

The green-emitting semiconductor laser is a milestone for many applications and will open up new markets, for example, in ultra-compact mobile RGB laser projectors.

In a statement the company said it started developing direct blue laser diodes for RGB (red green blue) laser projection in 2006. These are now used successfully in the first devices on the market. Based on the findings for the blue laser in the indium gallium nitride (InGaN) material system, the team managed to break through the barrier to green from a wavelength of 500 nm. In 2009, the company says that the team took over the technological leadership in direct green laser diodes of >515 nm with optical outputs of more than 50mW.

The Karl Heinz Beckurts Foundation grants the award annually on December 10 to honor outstanding scientific and technical achievements that give rise to discernible impetus for industrial innovations in Germany.
