Rohm's 120W laser diode for LiDAR: measures distance and spatial recognition

Japan-based semiconductor and electronics component leader Rohm has made available its new high-power laser diode targeting LiDAR-employing industrial equipment and consumer applications requiring distance measurement and spatial recognition. With this new device launch, Rohm is addressing growing market of LiDAR adoption in a wide range of robotic applications that require automation - including AGVs (Automated Guided Vehicles), robot vacuums, and autonomous vehicles to measure distance and recognize space. Rohm is improving it's laser diode device performance as per market trends in this area.
The new 120 Watt laser diode - the RLD90QZW8 is a 120W infrared high output laser diode developed for LiDAR used in distance measurement and spatial recognition in 3D ToF systems. Original device development technology allows ROHM to reduce the temperature dependence of the laser wavelength by 66% over general products, to just ⊿11.6nm (Ave. 0.10nm/°C). This makes it possible to narrow the bandpass filter while extending the detection range of LiDAR. At the same time, a uniform light intensity of 97% is achieved over the industry's smallest class of emission width of 270µm, representing a range of 264µm that contributes to higher resolution. Additional features that include high power-to-lig...
