AMS Osram launches new generation of LiDAR laser components for vehicles

On November 14th, AMS Osram announced the launch of a new 5-junction edge emitting laser, further enhancing the efficiency and reliability of LiDAR systems for autonomous vehicles. The LiDAR system can collect real-time 3D stereoscopic environmental information without being limited by lighting conditions, assisting vehicles in making safety judgments.

Compared with the previous three structure technology, this new laser provides higher optical peak power while consuming less current. The three junction laser has been able to increase the measurement distance by about 50% compared to traditional emitters, and the new five junction laser further breaks through the limitations. By vertically stacking five emission layers in a single chip structure, not only does it extend the detection distance, but it also improves overall energy efficiency. Lower resistance loss can reduce heat generation, simplify heat dissipation design, and is suitable for compact architectures in vehicles.

Tobias Hofmeier, Product Marketing Manager at AMS Osram, said, "With the new five junction laser, we assist car manufacturers in creating LiDAR systems that combine powerful performance, precise detection, high efficiency, and scalability. Its excellent detection distance, stability, and easy to integrate design will become an important driving force for the continuous advancement of autonomous driving technology. ”

For LiDAR system developers, this technology represents higher efficiency and lower system complexity. The new laser can operate at lower currents, reducing the burden on the driving circuit; Simultaneously integrated wavelength stabilization technology ensures consistent measurement results, maintaining stable performance even under temperature changes or harsh environments. This highly reliable, efficient, and scalable laser component will become a key foundation for the next generation of automotive sensing systems. The new five junction laser is supplied in bare crystal form, providing system developers with greater design flexibility while saving space and helping to create smaller and more efficient LiDAR modules.

For car manufacturers, longer measurement distances mean they can detect potential objects earlier - whether it's pedestrians crossing the road at night or malfunctioning vehicles in bends. Higher detection accuracy can improve object recognition accuracy and reduce false alarm rates; The improvement of energy efficiency makes system design more compact and cost-effective, and simplifies thermal management design. In addition, this SMT compatible packaged laser features a miniaturized design that can be quickly integrated into existing platforms, significantly reducing development time and accelerating the mass production of autonomous driving technology.

The application scope of LiDAR is rapidly expanding, from urban autonomous taxis and unmanned delivery vehicles to highway autonomous driving assistance systems (ADAS). The new five junction laser is expected to be launched globally in early 2026.
