Light is excellence - Discover the Visible InGaN Laser Diodes by OSRAM Opto Semiconductors

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 W 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.

"The PLPT9_450LA_E completes our broad portfolio of InGaN lasers with a 3 W 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.
