Long-range LiDAR systems' performance is improved for autonomous driving with an 8-channel, 915nm SMT pulsed laser.
Ams OSRAM's exclusive wavelength stabilization technology is used in the world's first AEC-Q102 rated 8-channel QFN package, which offers excellent performance and efficiency.
Based on more than two decades of pulsed laser technology expertise
Munich, Germany and Premstaetten, Austria (August 5, 2024) - Ams OSRAM (SIX: AMS), a world leader in intelligent sensors and emitters, is launching its most recent significant breakthrough to facilitate autonomous driving with its ground-breaking 8-channel pulsed laser. The laser increases the effectiveness and dependability of long-range LiDAR systems by streamlining system design and improving performance. LiDAR systems for autonomous driving vehicles, including trucks, passenger cars, and robo taxis, will use the SPL S8L91A_3 A01, a high-performance 8-channel 915nm SMT pulsed laser in a QFN package. Their ability to navigate, operate, and analyze data will all be improved by the new product.
For autonomous driving, the SPL S8L91A_3 A01 is intended to greatly enhance long-range, high-resolution LiDAR systems. An even wider range of infrared components from ams OSRAM are now available to system developers thanks to the world's first AEC-Q102 certified 8-channel EEL (edge-emitting laser) in a QFN package. With a peak optical power of 1000 watts and an efficiency of up to 30%, the new device provides a compelling performance.
One of the most talked-about future themes is autonomous driving. When it comes to developing autonomous driving, most system suppliers are certain that LiDAR is an absolute need. For more than 20 years, Ams OSRAM has led the industry in the development and manufacturing of pulsed infrared lasers for vehicle LiDAR. The fact that there are already over 20 million devices in use is a great indication of this in terms of quality and experience. The newest product in the series, the SPL S8L91A_3 A01, is based on a wealth of automotive LiDAR technology expertise.
With its monolithically integrated 8-channel architecture, the SPL S8L91A_3 A01 is a cutting-edge infrared high-power SMT laser specifically designed for LiDAR applications. This novel setup significantly improves the performance capabilities of long-range LiDAR systems, which are essential for autonomous highway driving, by delivering 125W each laser channel, or 1000W total peak optical power. Each of the laser's four separate addressable anodes is linked to two parallel laser channels that are in operation. The client has more freedom to create the final product because to this addressability.
By using a single laser module, the LiDAR sensor can be set up more compactly and effectively. This simplifies the design and production process by removing the need for many components to align. In addition to cutting down on development time, this integration greatly improves the final product's performance and dependability. Ams OSRAM's unique wavelength stabilization technology, which is included into the laser's architecture, reduces wavelength shifts brought on by temperature variations, increasing the LiDAR system's detection range and Signal-to-Noise Ratio (SNR).
The SPL S8L91A_3 A01 is designed to withstand the demanding requirements of the automobile sector. Its suitability for automotive applications is guaranteed by the fact that it has exceeded the AEC-Q qualifying criteria. The QFN packaging of the laser is essential to its sturdy construction, offering a long-lasting solution that satisfies the demands of automotive settings. To improve their operating, navigation, and data processing capabilities, the items may be included into LiDAR systems for autonomous driving vehicles, such as trucks, passenger automobiles, or robot taxis. Additionally, the new laser may improve performance in industrial applications including last-mile delivery, robots, smart cities, and monitoring.
"Our new 8-channel laser module is a game-changer for the autonomous driving industry," says Clemens Hofmann, ams OSRAM's Senior Principal Engineer for LIDAR. It improves performance and streamlines system design, increasing the efficacy and dependability of long-range LiDAR systems. Superior performance across a range of operating situations is ensured by integrating our cutting-edge wavelength stabilization technology.
This fall, the SPL S8L91A_3 A01 will be introduced.
