905nm Laser Transmitter for Beam Steering LiDAR System

2020.09.07

Focuslight has released a new high peak power 905nm pulsed laser module LE01, which is the market's first laser line generator for beam steering LiDAR transmitter. It is categorized under the LiDAR Tx L Product Line of Automotive BU. The major application is for beam steering LiDAR system used for autonomous driving, but it can also be used for 3D sensing and IR illumination applications. 

The unique advantages of this 905nm laser line generator are that by taking advantage of Focuslight cutting-edge long focal length fast axis collimation lens (FAC) and homogenizer (HOM), it can achieve less than 0.2° field of view (FOV) angle in fast axis and 20° FOV angle in slow axis with larger than 90% uniformity. Based on the specific requirement from different customers, the FOV angles and power could also be customized up to 160°.

Automotive-Grade Optical Components

  • Focuslight automotive-grade glass FAC

  • <0.2° x 20° uniform line beam

High Reliability

  • Built with automotive-grade EEL laser chips, packaging and optical components

  • Designed for > 100,000h lifetime with high reliability

LE01 Appearance

The high peak power 905nm pulsed laser module LE01 not only is featured for its performance but also has a very compact design. Moreover, an upgrade version, LE02 is going to be released soon, with even higher power and smaller FOV angle along fast axis.
