SUNNYVALE, Calif., June 4, 2012 — The PL TB450 high-power blue laser diode from Osram Opto Semiconductors is mounted in a compact TO-56 package and features optical power of 1.4 W, making it suitable for high-quality professional projectors such as those used in offices, conference rooms and home cinemas. Built on an indium-gallium-nitride substrate, it is also suited for medical applications and for laser systems for stage and decoration illumination.

Professional projectors with a luminous flux of more than 1000 lm are the main area of application. At 450 nm, the diode produces the blue laser light desired and, with 1.4 W at room temperature and a current of 1.2 A, the high optical power required. Operating temperature is from 0 to 70 °C.

Efficiency is 27% percent, so the temperature of the laser will rise only slightly when in use, giving it a long service life of up to 10,000 h at 40 °C in continuous operation.

There are various approaches to using the laser diode in a professional projector. Usually, red LEDs are combined with blue high-power lasers, and the green color emerges when the blue lasers excite a special phosphor to emit light. Red light can also be generated this way, so that the projector light source can be designed without red LEDs, if a smaller size is required.
