ROHM Unveils the RLD8BQAB3 Laser Diode

ROHM Co., Ltd., a prominent manufacturer in the semiconductor industry, has made a significant advancement in the field of high-power laser diodes with the introduction of the RLD8BQAB3 model. This new laser diode is specifically designed for use in LiDAR (Light Detection and Ranging) applications, particularly within advanced driver assistance systems (ADAS). With a remarkable output of 1 kW, this device is expected to vastly improve measurement distance and spatial recognition capabilities crucial for automation technologies.

Target Applications

The RLD8BQAB3 isn’t just limited to automotive uses; it also finds great potential in various consumer and industrial sectors. Notable applications include drones, robotic vacuum cleaners, automated guided vehicles (AGVs), and even service robots. The growing demand for precise distance measurement and long-range detection capabilities in these areas has prompted the development of such high-performance components.

Innovative Features

One of the standout features of the RLD8BQAB3 is its unique 125W, 8-channel array design. This configuration significantly enhances detection accuracy over longer ranges by emitting light in closely spaced intervals. Furthermore, ROHM's patented technology enables the diode to produce narrow laser emission widths, making it ideal for high-accuracy LiDAR systems.

A focus on compactness has also been achieved, as the infrared laser diode measures just 3.3 mm × 5.6 mm. Each of its eight emission areas, measuring 300 micrometers, is optimally mounted on a high-heat-dissipation substrate. An innovative glass cap, a first in the industry for surface-mount laser diodes, is used to ensure beam quality by reducing light scattering, a common issue seen with resin-encapsulated devices.

Remarkable Performance and Versatility

The RLD8BQAB3 laser diode offers exceptional versatility with flexible irradiation options, allowing both individual and simultaneous emissions. This vastly improves output consistency; in fact, ROHM claims that the new diode achieves an industry-leading 1kW-class output. Further elevating its performance, the device maintains uniform emission intensity across its width, as well as a low wavelength temperature dependence of just 0.1 nm/°C. Standard products typically exhibit a higher temperature variance, falling between 0.26 to 0.28 nm/°C.

In addition to its technical specifications, the array configuration of the RLD8BQAB3 minimizes emission gaps between channels, enhancing the efficiency of light usage in detecting objects at long distances. To improve this further, a bandpass filter is integrated, permitting only desired light signals to pass, thereby mitigating the influence of ambient light interference.

Availability and Compliance

Samples of the RLD8BQAB3 are currently available for interested parties, with further developments in progress to ensure compliance with automotive standards (AEC-Q102). This commitment to meeting rigorous industry standards reinforces ROHM's dedication to quality and performance.

About LiDAR

LiDAR technology operates by sending out laser light and measuring the time it takes for the light to return after hitting an object. This effective system is crucial for achieving accurate environmental mapping, autonomous navigation, and more. As the demand for LiDAR technology continues to rise, innovations like the RLD8BQAB3 from ROHM will play a significant role in transforming various industries.
