Osram PLPT9_450LA_E blue high-power laser

The PLPT9_450LA_E from Osram Opto Semiconductors is a multimode laser diode that is mounted in a hermetically sealed TO metal can package. The lasers combine a good form factor with high beam quality, making them suitable light sources for show lasers and stage lighting.

At a typical operating current of 2 A, the product achieves an optical power of 3 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 micrometres 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, according to the company.

The laser comes in Osram’s robust TO90 package. Compared to the first TO56 generation that included three pins, the 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, the integration of the laser into the final lighting solution is less complicated.

With easier cooling, an application range up to 85°C and an operating voltage of less than 5 V, Osram offers small and lightweight designs of high-quality lighting solutions for show lasers, endoscopy, professional laser torches and other numerous applications.
