Hamamatsu Photonics has developed a highly functional and reliable pulsed laser diode for in-vehicle LiDAR.
Mounted in a ceramic package with excellent heat dissipation, this new pulsed laser diode ensures stable operation even at high temperatures up to 105°C.

Hamamatsu Photonics succeeded in developing a “4-channel pulsed laser diode” that uses a ceramic package with excellent heat dissipation to ensure high reliability required for automotive applications and still emits stable light even in high temperature environments up to 105°C.

Using this new pulsed laser diode as the light source for in-vehicle LiDAR modules allows more accurate measurement of objects at far away distances and over wide areas. We will start shipping sample products of this new pulsed laser diode from next year to automotive manufacturers planning full-scale mass production of self-driving cars that are expected to be available in the near future.

This new pulsed laser diode will be on display at the Hamamatsu Photonics exhibition “PHOTON FAIR 2018” to be held for the first time in 5 years at Act City Hamamatsu (Naka-ku, Hamamatsu City, Japan) for 3 days from November 1 (Thursday).

A surveying technique that measures the distance to an object and its 3-dimensional information such as shape by irradiating the object with laser light and detecting he reflected light.
