Osram presents blue high-power laser for events


A new blue high-power laser from Osram is now expanding the range of options available to manufacturers of show lasers and stage spotlights.

The PLPT9_450LA_E from Osram Opto Semiconductors is a multimode laser diode that is mounted in a hermetically-sealed TO metal can package.
In terms of brightness, laser diodes offer some advantages over LEDs. At a typical operating current of 2 A, the PLPT9_450LA_E achieves an optical power of 3.0 watts and emits blue light with a wavelength of 447 nm. In a typical optical system, the laser light is focused at a point only a few micrometers in diameter. The laser can be directly used as a blue light source or in combination with a special phosphor for white conversion. The achieved luminance of the white light source is around three times higher than that of a comparable LED.
The PLPT9_450LA_E comes in the proven, robust TO90 package. Compared to the first TO56 generation that included three pins, the new TO90 package contains only two pins for contact. Thanks to the simpler cooling, the generated heat can be easily dissipated from the component. In addition, the integration of the laser into the final lighting solution is much less complicated.
