AMS Osram is launching an 8-channel SMT pulsed laser with a wavelength of 915 nm onto the market. The laser is intended to improve lidar systems for long-range applications in the field of autonomous driving.
The 915 nm 8-channel SMT pulsed laser is installed in an EC-Q102-qualified QFN housing.
AMS Osram AG
AMS Osram has launched a 915 nm 8-channel SMT pulsed laser for autonomous driving. Due to its simplified system design and higher power, the laser is intended to increase the effectiveness and reliability of lidar systems for long-range applications. The SPL S8L91A_3 A01 is a 915 nm 8-channel SMT pulsed laser in a QFN (Quad Flat No Leads Package) package. In the future, it is to be integrated into lidar systems for autonomous vehicles, such as cars and trucks as well as self-driving cabs (robotaxis). The new product is intended to improve the operation, navigation and data processing capabilities of these vehicles. The SPL S8L91A_3 A01 is due to be launched on the market this fall.
With the AEC-Q102 qualified 8-channel edge emitting laser (EEL) diode in a QFN package, system designers now have the option to choose from an even wider variety of infrared components from AMS Osram. The diode is said to offer a performance of 1,000 W peak optical power (125 W per laser channel) with an efficiency of around 30 %. The laser has four individually addressable anodes, with each anode connected to two laser channels operating in parallel.
Technology for Stabilizing the Wavelength
The use of only one laser housing is intended to enable a more compact and efficient design. The design of the laser incorporates AMS Osram's proprietary wavelength stabilization technology. This is said to minimize wavelength shifts due to temperature changes, which improves the signal-to-noise ratio (SNR) and extends the detection range.
