Laser Range Finding Solutions

PGA and PGEW series pulsed semiconductor lasers in the near IR are commonly used for long-distance time-of-flight or phase-shift range-finder or LIDAR systems. Excelitas offers a broad range of ideally-suited pulsed 905 nm laser designs including multi-cavity monolithic structures with up to 4 active areas per chip resulting in up to 100 W of peak optical output power. Physical stacking of laser chips is also possible, resulting in up to 300 W of peak optical output power.

Excelitas’ TPGA pulsed semiconductor laser produces very high peak optical pulses centered at a wavelength of 905 nm. The package design can emit light parallel or perpendicular to the mounting plane. Uses a multi-layer monolithic chip design. The laser diode is mounted on an FR4 substrate leadless laminate carrier (LLC) with excellent thermal management, intended for both surface mount applications and hybrid integration.

TPGA high power four channel pulsed semiconductor laser array for LIDAR and Range Finding. Very high peak optical pulses centered at a wavelength of 905 nm - a concentrated emitting source size for high power into aperture. Two versions available – one with the channels close together allowing the lasers to be operated as one large laser with no gaps between channels in the near field, the other version with each channel individually addressable. The laser diode is mounted on an FR4 substrate leadless laminate carrier (LLC) with excellent thermal management , ideally suited for both surface mount applications and hybrid integration. The encapsulate material is a molded epoxy resin for low cost and high-volume manufacturing.

The Excelitas C30737 series silicon APDs provide high responsivity between 500 nm and 1000 nm as well as extremely fast rise times at all wavelengths, with a frequency response above 1 GHz for bandwidth-optimised versions. The C30724, as a low gain APD, can be operated at a fixed voltage without the need for temperature compensation.
