OSRAM's new 905 nm edge-emitting laser diode is low-cost
The SPL PL90AT03's high peak output power and narrow 110 m aperture provide superior performance.
- Ideal for 3D sensing applications such as robotics, factory automation, drones, range finders and smart cities and logistics
- Cost-effective plastic package for consumer and industry applications supporting short pulses with a duration from a few ns to 100 ns
OSRAM, a global leader in optical solutions, has added a higher-performance infrared laser targeting cost-conscious consumer and other applications with the introduction of a 75 W edge- emitting laser in a cost-effective radial plastic package.
The new SPL PL90AT03 edge-emitting laser diode’s low-cost plastic package is ideal for use in high-volume applications. Featuring the same footprint as the previous generation of SPL PL90 series laser diodes, the SPL PL90AT03 provides an easy upgrade to higher efficiency, thanks to its state-of-the-art chip technology. SPL PL90AT03 also produces a narrower emission width and enables easier optical design because of the device’s 50 percent 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 30 ns pulse of 75 W at the device’s maximum forward current of 25 A. The laser diode can produce short laser pulses ranging from a few ns to 100 ns.
The high optical power output in a narrow emission area makes the SPL PL90AT03 ideal 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 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.
High optical performance
The pulsed laser SPL PL90AT03 features a peak wavelength of 905 nm and a spectral bandwidth (FWHM) of 5 nm. Beam divergence is just 12° (parallel) x 25° (perpendicular), enabling efficient beam shaping with its small 110 μm aperture.
The SPL PL90AT03 is now available. For more information, go here.
