Coherent Corp. has announced the introduction of its 905 nm triple-junction edge-emitting semiconductor lasers for light detection and ranging (LiDAR) in industrial applications.
Range-finding devices embedded in binoculars and increasingly 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 new 905 nm semiconductor lasers from Coherent feature a triple-junction design that enables them to efficiently emit up to 100 W of optical power in nanosecond pulses. The lasers are qualified to the stringent JEDEC JESD22-A10x standard for industrial applications.
Built in a robust and hermetically sealed TO-56 package, the triple-junction lasers emit three times the optical power per chip area compared with single-junction devices, resulting in powers of up to 100 W at 40 A pulsed operation. They 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.
