These high-power, infrared SMT components feature a 905 nm laser wavelength that's suitable for use in autonomous vehicles and other Light Detection and Ranging (LiDAR) applications.
The SPL S1L90A and SPL S4L90A lasers offer a typical output of 120W at 40 A per channel, at up to 33 percent efficiency. They feature low thermal resistance, allowing heat to dissipate easily from components even when operating at high currents.
The lasers are available in the single-channel SPL S1L90A version and the four-channel SPL S4L90A version, providing varying levels of range and optical power. The four-channel laser, available to order from Mouser, delivers optical power at 480W, making them suitable for an extended detection range.
The high-power SPL S1L90A and SPL S4L90A lasers enable short pulse widths of around 2 ns or less. The lasers are qualified according to AEC-Q102 automotive guidelines, and their compact form factor makes them suitable 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.
