Blue high-power laser from OSRAM provides breathtaking light shows
The PLPT9_450LA_E expands OSRAM’s laser portfolio for lighting applications and is 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. Lasers combine an outstanding form factor with excellent beam quality – making them particularly suitable light sources for show lasers and stage lighting.
Bright and robust, better than LEDs
In terms of brightness, laser diodes offer some advantages over LEDs. At a typical operating current of 2A, the PLPT9_450LA_E achieves an optical power of 3.0 watts and emits blue light with a wavelength of 447nm. 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.
Application range up to 85°C
"The PLPT9_450LA_E completes OSRAM's broad portfolio of InGaN lasers with a 3-Watt version. Thanks to the easier cooling, an application range up to 85° C and an operating voltage of less than 5 V, 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," explains Christoph Walter, Product Manager for Visualization & Lasers at OSRAM Opto Semiconductors.
OSRAM laser diode product range
The OSRAM laser diode product range includes green and blue laser diodes packaged in extremely compact, 3.8mm diameter TO cans. The diodes feature low beam divergence, long lifetime and excellent stability across a broad temperature range. The OSRAM laser diode product range is available from The Optoelectronics Company Ltd.
