ROHM's 1kW Class Laser Diode: Revolutionizing LiDAR Technology

ROHM, a leading semiconductor manufacturer, has recently developed a groundbreaking 1kW class high-power infrared laser diode, the RLD8BQAB3. This innovative product is set to revolutionize LiDAR technology, enabling enhanced distance measurement and spatial recognition across various applications. Let's delve into the key features and benefits of this remarkable laser diode.

The RLD8BQAB3 is an ultra-compact, surface-mount, high-output 125W × 8ch infrared laser diode designed for LiDAR applications that utilize 3D ToF systems. Its optimized design features eight emission areas, each 300µm wide, per element, installed on a submount affixed to a high heat dissipation substrate. This configuration allows for efficient heat management, ensuring stable operation even at high power outputs.

One of the standout features of the RLD8BQAB3 is its clear glass cap, an industry first for a surface-mount laser diode. This cap eliminates the risk of light scattering caused by scratches during dicing, ensuring high beam quality and maintaining the accuracy of LiDAR systems. Additionally, the common cathode wiring enables flexible irradiation options, including individual and simultaneous emissions, allowing for tailored LiDAR solutions based on specific application needs.

The RLD8BQAB3 retains the key features of ROHM's conventional laser diodes, such as uniform emission intensity across the emission width and a low wavelength temperature dependence of 0.1nm/°C. These features contribute to the reliability and consistency of the laser diode in various applications, even under fluctuating temperature conditions.

Moreover, the array configuration of the RLD8BQAB3 narrows the regions of reduced emission intensity between channels, while the bandpass filter minimizes the effects of ambient light noise from the sun and other sources. These features contribute to long-distance detection and high-definition LiDAR functionality, making the RLD8BQAB3 an ideal solution for industries such as automotive, consumer electronics, and industrial automation.

In conclusion, ROHM's 1kW class high-power infrared laser diode, the RLD8BQAB3, is a game-changer in the LiDAR technology landscape. Its innovative features, such as the clear glass cap, flexible irradiation options, and optimized design, enable enhanced distance measurement and spatial recognition across various applications. As LiDAR adoption continues to grow, the RLD8BQAB3 is poised to become an essential component in the development of cutting-edge LiDAR systems.
