In autonomous driving applications, SPL S8L91A_3 A01 is used to significantly enhance long-range high-resolution LiDAR systems. With AEC-Q102 certification and an 8-channel EEL (edge emitting laser) packaged in QFN, AMS Osram now offers a more diverse range of infrared components for system developers to choose from. The peak optical power of this new product is 1000W, with an efficiency of up to 30% and outstanding performance.

Autonomous driving is one of the most discussed topics about the future, and most system suppliers firmly believe that LiDAR is essential for advanced autonomous driving. For over 20 years, in the field of development and production of automotive LiDAR pulse infrared lasers, AMS Osram has been an important participant in the autonomous driving market - delivering over 20 million units, with experience and quality fully recognized by the market. SPL S8L91A_3 A01 is the latest product lineup launched based on the company's rich experience in automotive LiDAR technology.

SPL S8L91A_3 A01 is an advanced infrared high-power SMT laser tailored for laser radar applications. It adopts a single-chip integrated 8-channel design, with each laser channel providing 125W of power, resulting in a total peak optical power of 1000W, greatly enhancing the performance of long-distance laser radar systems that are crucial for highway autonomous driving. This laser has 4 individually addressable anodes, each connected to two parallel operating laser channels. Thanks to the addressing function, customers are able to flexibly design the final product.

The use of integrated laser packaging can achieve more compact and efficient settings, without the need for alignment between multiple components, thus simplifying the design and manufacturing process. This integration not only shortens development time, but also significantly improves the reliability and performance of the final product. The design of this laser adopts the proprietary wavelength stabilization technology of AMS Osram, which can significantly reduce wavelength drift caused by temperature changes, thereby improving the signal-to-noise ratio (SNR) of the laser radar system and expanding the detection range.

SPL S8L91A_3 A01 is designed to meet the strict requirements of the automotive industry, with performance specifications that meet and exceed AEC-Q certification standards. The QFN packaging of this laser is key to ensuring reliable design and providing a durable solution to meet the challenges of automotive environments. In addition to the laser radar system that can be widely used in autonomous vehicle, the new laser can be used in industrial laser radar, which can improve the performance of applications such as robots, security monitoring, smart cities and the last mile delivery.

Our new 8-channel laser module will revolutionize the autonomous driving industry. It simplifies system design and improves performance, making long-range LiDAR systems more effective and reliable. By integrating our advanced wavelength stabilization technology, we can ensure excellent performance under different working conditions, "said Clemens Hofmann, Senior Chief Engineer of AMS Osram Lidar
SPL S8L91A_3 A01 will be launched this autumn.
