Osram introduces new laser diode

PLPT9 450D_E A01

The PLPT9 450D_E A01 laser diode’s compact dimensions enable headlights to be made much smaller in the future, opening up several new design possibilities and performance values for applications in car headlights.

Osram Opto Semiconductors' second-generation blue multi-mode laser diode, PLPT9 450D_E A01, reportedly doubles the range of previous LED solutions up to 600 m (1969 ft). It is also intended to simplify system design when used in the auxiliary high beam lights of vehicles.

“The new PLPT9 450D_E A01 laser diode is the perfect example of our commitment to bringing smaller, better, and brighter lighting components to the automotive industry,” said Rajeev Thakur, Regional Marketing Manager at Osram Opto Semiconductors. “This powerful laser is remarkably compact, making it an impressive advancement in automotive lighting.”

At a typical operating current of 2.2 A, the blue PLPT9 450D_E A01 laser reaches an optical output of 3.5 W and emits blue light at a wavelength of 447 nm. With the help of appropriate optics, the laser light is focused on a point only a few micrometers in diameter. A special phosphor converter transforms the blue light into the white light that is required for front lighting applications.

The PLPT9 450D_E A01 laser diode is qualified for use in cars and approved for an operating temperature range of -40°C to 120°C. Compared to the first generation with three pins, the second-generation TO90 package contains only two pins, which allows for easier connection and heat dissipation. The laser’s compact dimensions of 9 mm (0.35 in) in diameter and height of < 4.5 mm (0.18 in) (without contact pins) enable headlights to be made much smaller in the future.
