Osram Opto launches direct-emitting green laser diodes
Osram Opto Semiconductors GmbH of Regensburg, Germany says that it is now offering its first direct-emitting green diode lasers. The two compact indium gallium nitride (InGaN) laser diodes have optical output powers of 30mW and 50mW, respectively (at 25°C), as well as high beam quality, which is key to the development of miniature projectors for mobile devices such as smartphones and cameras, adds the firm. Other applications include projection units for laser shows, point lasers and line lasers.
Direct green diode lasers are a key step toward powerful pico projectors, eliminating the laborious method of producing green light by doubling the frequency of an infrared laser. The new technology also enables high color rendering and contrast to be achieved, says Osram Opto.
The new PL 520 laser diode’s wavelength range of 515-530nm produces the appropriate green colour for projection applications, the firm notes. Optical output is 50mW and efficiency is typically 5-6% at present. In addition, the PL 515 laser diode offers an output of 30mW in the wavelength range 510-530nm. With a TO-38 package diameter of just 3.8mm the lasers can enable the dimensions of projection units to be reduced considerably. “The commercial breakthrough for compact laser projectors is closer than ever before,” reckons Stephan Haneder, marketing manager for Consumer Lasers at Osram Opto....
