Osram launches 3W blue laser for stage lighting applications
Osram Opto Semiconductors GmbH of Regensburg, Germany has launched a new blue high-power laser to expand the range of options available to manufacturers of show lasers and stage spotlights.
The PLPT9_450LA_E is a multi-mode laser diode mounted in a hermetically sealed TO metal can package. Lasers combine an outstanding form factor with excellent beam quality, making them particularly suitable light sources for show lasers and stage lighting, says Osram.
Offering advantages over LEDs in terms of brightness, the PLPT9_450LA_E laser diode achieves an optical power of 3W (at a typical operating current of 2A) and emits blue light with a wavelength of 447nm. In a typical optical system, the laser light is focused to a point only a few microns 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 with the first TO56 generation that included three pins, the new TO90 package contains only two pins for contact. Due to the simpler cooling, the generated heat can be easily dissipated from the component. In addition, integration of the laser into the final lighting solution is much less complicated.
“The PLPT9_450LA_E completes our broad portfolio of indium gallium nitride (InGaN) lasers with a 3W version,” says Christoph Walter, product manager for Visualization & Lasers. “Thanks to the easier cooling, an application range up to 85°C and an operating voltage of less than 5V, we are able to offer our customers particularly small and lightweight designs of high-quality lighting solutions for show lasers, endoscopy, professional laser torches and other numerous applications.”
