Laser diode offers solution for 3D sensing applications

Mouser now stocks the SPL PL90AT03 laser diode from ams OSRAM. The laser diode delivers 75W of peak power and a narrow 110µm aperture, providing outstanding performance for 3D sensing, Lidar and ToF applications. The laser diode is a cost-effective option for applications including factory automation, robotics, security and access control, and appliances and tools.

The radial T1 3/4 laser diode is an excellent option for short laser pulses from 1ns to 100ns. The single-channel diode provides the company's multi-junction technology, which offers three vertically stacked emitters in a single laser die. This multi-junction solution permits the laser to deliver an optical peak output power of 75W in a 30ns pulse at the device's maximum forward current of 25A.

The laser diode is housed in a cost-effective plastic package, making it an excellent selection for high-volume applications. The device provides a peak wavelength of 905nm and a spectral bandwidth of 5nm. The device supports efficient beam shaping with a beam divergence of 12° (parallel) x 25° (perpendicular).

The high optical power output in a narrow emission area makes it suited to ranging and distance-measurement applications that run over long distances, such as robots, drones, smart home and factory automation equipment. In ToF sensing and LiDAR applications, the device's high performance allows the production of more precise and accurate depth maps for 3D optical sensing and simultaneous localisation and mapping systems.
