Some correction here. FMCW lidar does not need fiber lasers. In fact most fiber lasers are actually very difficult to frequency sweep internally. Typical lasers used in swept wavelength interferometry (which is really the same thing) are so-called external cavity lasers, which rely on photodiodes + external cavity e.g. through a wavelength selective feedback (still comparably expensive though).

Baraja selling point was AFAIK that they used a integrated swept laser source (they typically have lower coherence but you can work around that in DSP).
