905nm triple junction lasers for industrial LiDAR
Coherent has launched a high performance 905 nm triple-junction edge-emitting semiconductor lasers in a TO package for light detection and ranging (LiDAR) in industrial applications.
Range-finding devices embedded in autonomous robots that accomplish complex tasks, such as handling, sorting, mapping, and navigating, are accelerating the demand for LiDAR-based depth sensing using components that perform efficiently and reliably, even in the most extreme environments.
The triple junction edge emitting 905nm semiconductor lasers can emit up to 100 W of optical power at 40A in nanosecond pulses. The lasers are qualified to the stringent JEDEC JESD22-A10x standard for industrial applications.

“What customers appreciate is that we will be able to achieve significant economies of scale by migrating manufacturing of this new laser diode platform to our existing 6-inch gallium arsenide platform,” said Dr. Karlheinz Gulden, Senior VP, Laser Components & Subsystems Business Unit.
“It is the only technology platform of its kind to have pushed the frontiers of both manufacturing scale and field reliability, underpinning semiconductor lasers for high-volume consumer electronics and industrial devices, as well as for optical communications equipment deployed undersea,” he said.
The lasers are built in a robust and hermetically sealed TO-56 package and enable direct time-of-flight LiDAR systems in a wide variety of mission-critical robots exposed to challenging environments. Applications include warehouse logistics, consumer appliances, last-mile delivery, crop harvesting, land surveying, and safety monitoring.
