Excelitas Technologies Introduces 1X4 Pulsed Laser Diode Array for LiDAR in Autonomous Vehicle Applications

WALTHAM, MA --- Excelitas Technologies Corp. introduces the 1X4 Pulsed Laser Diode Array for LiDAR applications. The new laser array combines Excelitas’ field-proven high-efficiency, multi-cavity laser chip technology with small form-factor surface mount device (SMD) packaging for applications requiring high reliability such as autonomous vehicles and drones.

The Excelitas 1X4 Pulsed Laser Diode Array constitutes a key building block of LiDAR systems, which have become an indispensable detection technology for autonomous vehicles. Unlike single-pixel lasers, the 1X4 linear configuration enables each pixel to be situated in very close proximity to its neighbor – minimizing space requirements in the assembly and enabling the use of smaller, less costly optical components. It is fully compatible with SMD pick-and-place and reflow soldering equipment, allowing it to seamlessly integrate into high-volume, low-cost assembly lines. Each laser pixel can have up to four emitting stripes, enabling very high per-channel optical power levels in excess of 85 W for long-range detection with minimal power consumption. These lasers can sustain large reverse voltage levels, with rise times of less than 5 ns that can be achieved with proper drive electronics which can also be provided by Excelitas.

The standard 1X4 Pulsed Laser Diode Array can be customized to meet each customer’s optical system requirements. Variables such as the number of elements, element spacing, stripe width, channel power output and package footprint can be adjusted to enable minimized losses, longer range detection and reduced power consumption.
