ams OSRAM launches compact surface-mount edge-emitting laser with narrow 110µm aperture
ams OSRAM GmbH of Premstätten, Austria and Munich, Germany has extended its edge-emiting laser diode portfolio by introducing a compact surface-mount device with a small aperture size. The SPL S1L90H_3 offers improved performance at long range and easier optical integration in light detection & ranging (LiDAR) and long-distance industrial ranging applications.
The SPL S1L90H_3 is said to be one of the first surface-mount edge-emitting lasers to have an aperture as small as 110µm. The small aperture enables the application to produce a narrow beam. The 905nm infrared technology is optimized for short-pulsed LiDAR applications such as drones and robots as well as in building and factory automation equipment.
The single-channel SPL S1L90H_3 features ams OSRAM’s multi-junction technology, consisting of three vertically stacked emitters in a single laser die mounted inside the device’s 2.3mm x 2.0mm x 0.69mm package. This enables the laser 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, notes the firm.
“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,” says Jouni Riihimaeki, product marketing manager for industrial lasers. “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.”
Optimized package design
The optimized, power-efficient pulsed laser SPL S1L90H_3 enables a maximum pulse width of 50ns. Beam divergence is just 10° (parallel) x 25° (perpendicular), enabling efficient beam shaping with its small aperture.
The SPL S1L90H_3’s inductance-optimized package is suitable for pulses shorter than 2ns. The robust surface-mount package is suitable 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.
