Excelitas has released the Surface Mount 905nm Pulsed Semiconductor Laser (SMD Laser), offering the capability of automated pick-and-place high-volume assembly. The SMD design delivers higher beam placement accuracy than a lead-frame, plastic packaged laser at comparable price points.
With a patented, ultra-compact, surface mount-compatible design, the new lasers can emit light either perpendicular or parallel to the mounting plane to meet the demand for high-volume, cost-effective lasers for commercial applications, including LIDAR, time-of-flight (ToF), range finding, safety light curtains, adaptive cruise control and laser therapy.
Featuring a multi-layer monolithic design, Excelitas’ pulsed semiconductor lasers produce very high optical pulses centered at a wavelength of 905nm. The laser diode chip is mounted on an FR4 leadless laminate carrier (LLC) substrate and encapsulated to provide excellent thermal management. The encapsulate material is a moulded epoxy resin for low-cost and high-volume manufacturing.
Key features include multi-cavity lasers for concentrating emitting source size, quantum well structure, high-peak pulsed power into aperture, excellent power stability with temperature, and RoHS compliance.
In addition to standard optical power outputs, the new Surface Mount 905nm Pulsed Semiconductor Lasers’ power output can be customised to achieve higher yields for end users.
