ams OSRAM adds 905nm edge-emitting laser with low-cost plastic package for consumer and industry applications

ams OSRAM GmbH of Premstätten, Austria and Munich, Germany has added a higher-performance infrared laser targeting cost-conscious consumer and other applications with the introduction of a 75W edge-emitting laser in a cost-effective radial plastic package. The firm says that the SPL PL90AT03’s high peak output power and narrow 110µm aperture result in superior performance in long-distance ranging applications and easier optical integration.

The new edge-emitting laser diode’s low-cost plastic package is suitable for use in high-volume applications. Featuring the same footprint as the previous generation of SPL PL90 series laser diodes, the SPL PL90AT03 is said to provide an easy upgrade to higher efficiency, due to its state-of-the-art chip technology. It also produces a narrower emission width and enables easier optical design because of the device’s 50% smaller aperture versus its predecessor.

The single-channel SPL PL90AT03 features ams OSRAM multi-junction technology, consisting of three vertically stacked emitters in a single laser die mounted inside a radial plastic package. This technology enables the laser to produce optical peak output power in a 30ns pulse of 75W at the device’s maximum forward current of 25A. The laser diode can produce short laser pulses ranging from a few ns to 100ns.

Available now, the SPL PL90AT03 pulsed laser features a peak wavelength of 905nm and a spectral bandwidth (FWHM) of 5nm. Beam divergence is just 12° (parallel) x 25° (perpendicular), enabling efficient beam shaping with its small 110µm aperture.

The high optical power output in a narrow emission area makes the SPL PL90AT03 suitable for ranging and distance-measurement applications that operate over long distance, such as robots, drones, as well as home and factory automation equipment. In time-of-flight (ToF) sensing and LiDAR applications, the high performance of the SPL PL90AT03 enables the production of more precise and accurate depth maps for 3D optical sensing and simultaneous localization and mapping (SLAM) systems.

“The growing ams OSRAM portfolio of high-performance edge-emitting IR lasers now includes a new option for customers that need a low-cost package,” says Jouni Riihimaeki, product marketing manager for industrial lasers. “The SPL PL90AT03 features the narrow aperture and high output power of other edge-emitting lasers in the family, but with a radial plastic package that is ideal for high-volume applications.”
