Mouser Electronics is now shipping the SPL S1L90A and SPL S4L90A lasers from Osram Opto Semiconductors.

The high-power, infrared SMT components feature a 905 nm laser wavelength suitable for use in autonomous vehicles and other Light Detection and Ranging (LiDAR) applications.

The lasers offer a typical output of 120 W at 40 A per channel, at up to 33% efficiency.

They feature low thermal resistance, allowing heat to dissipate easily from components even when operating at high currents.

Two versions are available.

The single-channel SPL S1L90A version and the four-channel SPL S4L90A provide varying levels of range and optical power. The four-channel laser delivers exceptional optical power at 480 W, suitable for an extended detection range.

Both lasers enable short pulse widths of around 2 ns or less.

They are qualified according to AEC-Q102 automotive guidelines, and their compact form factor makes them an ideal choice for limited-space designs as well as industrial sensing, control and automation, CCTV surveillance, 3D sensing, and pedestrian protection applications.

The package design ensures precise mechanical alignment during assembly, as well as a very low inductance to ensure short pulses for best results in high- and low-volume applications.
