Lasers for Lidar: Monolithic multichannel laser moves automotive lidar toward practical use
A four-channel laser and ultrafast driver delivers more than 480 W peak power in 2 ns pulses.
The driving force behind nearly all of today’s autonomous vehicles is the extraordinary, high-powered lasers driving lidar (light detection and ranging) systems. Lidar, featuring infrared lasers, navigates autonomous vehicles by creating a real-time, 3D image of the world. Pulsed lasers, along with single-pixel sensors or high-powered laser flash illumination using time of flight (TOF) cameras, are used to create the 3D images. The system measures the travel time of laser light from the autonomous vehicle to the target and back to the vehicle…
