The company says the laser is one of the first of its kind to have an aperture as small as 110 µm. The small aperture enables the application to produce a narrow beam. The 905 nm infrared technology is optimized for short-pulsed LiDAR applications.
The single-channel laser features ams OSRAM multi-junction technology, consisting of three vertically stacked emitters in a single laser die which is mounted inside the device’s 2.3 mm x 2.0 mm x 0.69 mm package. This technology enables it to produce peak output power of 65W. These features result in better illumination of the target area at long range in distance measurement, 3D optical sensing and simultaneous localization and mapping (SLAM) applications. This is valuable in products such as drones and robots, as well as in building and factory automation equipment.
“High volume consumer and industrial products need the convenience of a laser in a small surface-mount package that can be assembled by automated production equipment. Now the SPL S1L90H_3 extends our portfolio to include a lower-power surface-mount device for industrial markets, and with an aperture half the size of previous devices,” said Jouni Riihimaeki, Product Marketing Manager for industrial lasers at ams OSRAM.
Optimized package design
The optimized, power-efficient pulsed laser SPL S1L90H_3 enables a maximum pulse width of 50 ns. Beam divergence is just 10° (parallel) x 25° (perpendicular), enabling efficient beam shaping with its small aperture. Its inductance-optimized package is suitable for pulses shorter than 2 ns. The robust surface-mount package is ideal for use in industrial environments as well as in consumer applications and home and building automation. It is specified for corrosion robustness to class 3B, and offers low thermal resistance for easier system thermal design.
