Shanghai, China, November 14, 2025 - AMS Osram (SIX: AMS), a global leader in lighting and sensing innovation, today announced the launch of a new five-junction edge-emitting laser, leading the performance of lidar systems to a new level. The realization of autonomous driving cannot do without sensor technology that can provide precise, reliable and long-range detection at all times. The liDAR system is not restricted by lighting conditions and can obtain three-dimensional environmental information at any time, and achieve real-time safety decision-making.

Compared with the previous three-junction technology, the peak power of the new laser launched by AMS Osram this time has significantly increased, while the power consumption is lower. The traditional three-junction laser has increased the detection distance by 50% compared to conventional emitters, while the five-junction laser has made a further breakthrough: with five vertically stacked emission layers integrated in a single-chip structure, it not only significantly expands the detection range but also significantly optimizes energy efficiency performance. Meanwhile, its low resistance loss can reduce heat generation, thereby lowering the complexity of heat dissipation design. This is undoubtedly a major advantage in the compact car architecture.
Tobias Hofmeier, the product marketing manager of AMS Osram, said: "Our five-junction laser helps automakers create lidar solutions that are powerful in performance, precise in detection, energy-efficient and flexible in expansion." Its outstanding detection range, excellent stability and convenient integration will become the key driving force for accelerating the future implementation of autonomous driving.
For developers of lidar systems, the introduction of the new five-junction laser means that it can reduce the complexity of the system while achieving a qualitative leap in system performance. This laser has a lower operating current, reducing the demand for driving electronic components. Meanwhile, the integrated wavelength stabilization technology ensures the consistency of measurement results, even under temperature changes or harsh environmental conditions. This provides a reliable, efficient and scalable core component for the next-generation automotive sensor system. The new five-junction laser is supplied in bare crystal form. With this solution, system developers can achieve more flexible designs, save valuable space at the same time, and help create more sophisticated and efficient lidar modules.

For automakers, the new five-junction edge-emitting laser launched by AMS Osram holds profound strategic value and industry impact. This device can achieve a longer detection distance, which means the system can detect the target earlier - whether it is a pedestrian crossing the road at night or a faulty vehicle at a curve. Meanwhile, its higher detection accuracy helps to enhance the accuracy of target classification, thereby effectively reducing false alarms. In terms of energy efficiency, the improvement of new devices enables the system design to be more compact and cost optimized, while simplifying the thermal management solution. In addition, its compact chip size enables rapid and seamless integration on existing platforms, significantly shortening the development cycle and facilitating rapid large-scale mass production.
Lidar technology is no longer confined to high-end vehicle models. Whether it is self-driving taxis shuttling through urban environments, automated delivery vehicles, or advanced driver assistance systems (ADAS) at the highway level, their application scope is expanding rapidly. The improvement in detection distance and accuracy not only optimizes the ability to detect and classify target objects, but also empowers automakers to increase the upper limit of autonomous driving speed. This opens up new possibilities for highway driving and advanced driver assistance systems, while ensuring that safety and system reliability are not affected.
Ams Osram's new five-junction laser will be available globally in early 2026. For more product information, please visit the official website.
