Abstract
We demonstrate a C-band gain-switched seed laser intended for a EDFA-based fiber laser meeting the performance, footprint, robustness, and cost targets for volume time-of-flight LiDAR systems. The technology reported here leverages Freedom Photonics high-power DFBs coupled with a Black Forest Engineering control ASIC in a low-inductance package. As a result, the overall package is a compact form factor that can fit within a 16-pin butterfly package. To date, our 1550 nm seed technology delivers more than 2.5 nJ pulse energy for a 480KHz repetition rate on a 4 ns pulse, which is 30 times higher than conventional seed lasers. This technology is the first of its kind to realize a 1550 nm high-pulse energy seed laser for volume deployment of time-of-flight fiber-laser-based LiDAR systems.
