High-Output RLD8BQAB3 Infrared Laser Diode for LiDAR in ADAS and Robotics Applications

ROHM has developed a new high-output laser diode called the RLD8BQAB3 designed for use in systems that need accurate measurement of the distance and spatial recognition. It is used in LiDAR (Light Detection and Ranging), which is the technology used in Advanced Driver Assistance Systems (ADAS), drones, robot vacuum cleaners, Automated Guided Vehicles (AGVs), and service robots.

Rohm has been improving their laser diodes over the years. In 2019 they introduced a 25W output laser, followed by a 120W laser in 2023. Now they have launched RLD8BQAB3, which provides a 125W output. It is a compact, surface-mounted component, easy to install. It includes an 8 channel infrared laser diode for LiDAR applications that use 3D ToF systems to measure the distance and spatial orientation.

RLD8BQAB3 has a glass cover and has the ability to spread or focus the beams into a smaller or larger area depending on its use. RLD8BQAB3 has the ability to maintain uniform light intensity, and the laser's performance is less affected by temperature changes, with only a small shift in wavelength (0.1nm/°C). It also includes a special filter that helps block out unwanted light from sources like the sun, ensuring that the laser can work well even in bright environments.

Features of RLD8BQAB3 

• High output power: 125W per channel, 1kW total output (8 channels).

• Ultra-compact design: Surface mountable, space-efficient.

• Clear glass cap: Prevents light scattering and ensures high beam quality.

• Low wavelength temperature dependence: Stable performance with minimal wavelength shifts.

• Bandpass filter: Reduces ambient light interference for precise long-distance detection.

Applications of RLD8BQAB3 

• Advanced Driver Assistance Systems (ADAS)

• LiDAR systems

• Drones

• Automated Guided Vehicles (AGVs)

• Robot vacuum cleaners
