Mini laser for mini projectorsOSRAM's blue laser diode
An optimized TO38 package makes the blue laser diode from OSRAM Opto Semiconductors the smallest in its class. This takes the world one step closer to a vision of tiny projectors that can be integrated into mobile devices such as cell phones and digital cameras. Lasers are the first choice as light sources for these applications. They convert mobile devices into high-performance multifunctional devices that can not only record images but also present them in razor sharp detail.
With the development of the blue laser OSRAM Opto Semiconductors is another step closer to the vision of a projector integrated in a cell phone.
The blue laser has a wavelength of 450 nm and an output of 50 mW. The voltage is 5.5 V, and the slope efficiency 0.9 W/A. It combines all the important properties for mini projectors such as small size, high efficiency and good visibility of the blue light. As a ridge laser it also has an excellent beam quality and therefore needs only relatively simple small optics to shape the beam. According to Dr. Thomas Höfer, Head of Laser Projection at OSRAM Opto Semiconductors, “Our newly developed blue laser is a further step in our quest to enable miniaturized projectors that can be fully integrated in mobile devices.”
Mobile devices currently available on the market can produce and download high-quality photos and video clips. Integrated laser projectors will enable this content to be viewed also in high quality on almost any surface.
Lasers represent the next milestone in the development of mobile devices and have a promising future in terms of integrating projection modules. They will be appreciated by end customers for their extremely low power requirements and compact dimensions. They also offer exceptionally vibrant colors and high contrast, and they always produce sharp images irrespective of the distance over which the images are projected.
OSRAM Opto Semiconductors is also developing red and green lasers. The red laser, like the blue laser, will be designed as a direct semiconductor laser. Green lasers will be implemented using frequency doubling.

Ben,
ReplyDeleteThat looks very similar to the light source in the Science Channel video in your next post down. It's at 3:15 in the video.
Keep up the good work.
