Excelitas Technologies® Corp. of Waltham, Massachusetts USA, has introduced the 1X4 Pulsed Laser Diode Array for LiDAR applications. The new laser array combines Excelitas’ high-efficiency, multi-cavity laser chip technology with small form-factor surface mount device (SMD) packaging. The company created the array for applications requiring high reliability including autonomous vehicles and drones.
Unlike single-pixel lasers, the 1X4 linear configuration enables each pixel to be situated in very close proximity to its neighbor. Excelitas says that the configuration minimizes space requirements in the assembly and enables the use of smaller and less costly optics.
For seamless integration into high-volume, low-cost assembly lines, the laser array is fully compatible with SMD pick-and-place and reflow soldering equipment.
The device can be used for long-range detection with minimal power consumption because each laser pixel can have up to four emitting stripes that can enable very high per-channel optical power levels over 85 W. With proper drive components that can also come from Excelitas, the lasers can sustain high reverse voltage levels, with rising times of less than 5 ns.
Excelitas can customize the standard 1X4 Pulsed Laser Diode Array to meet each customer’s optical system requirements. Through this customization, the company can adjust the number of elements, element spacing, stripe width, channel power output and package footprint to minimize losses and enable longer range detection despite reduced power consumption.
“Excelitas is actively involved in LiDAR for autonomous vehicles, so we are excited to announce the new 1X4 Pulsed Laser Diode Array,” said Denis Boudreau, Product Leader at Excelitas Technologies. “This new laser array combines multi-cavity lasers and SMD packaging capabilities to address OEM design Engineers’ need for a high-performance, customizable solution that enables the development of next-generation LiDAR systems.”
Excelitas Technologies will debut the new 1X4 Pulsed Laser Diode Array at Photonics West in San Francisco, California, January 31 – February 2, 2017.
