Compared with semiconductor lasers, single frequency fiber lasers have lower phase noise and frequency noise, which will bring benefits to coherent LiDAR, especially to improve the signal-to-noise ratio of the system. Connet uses CoSF-D low noise single frequency fiber laser as the seed laser, and the output power is increased to 2W through the cascaded low noise polarization-maintaining fiber amplifier. CoWIND series high power single frequency fiber laser modules are ideal designed for coherent Doppler wind measurement LiDAR.


The CoWIND continuous working single frequency fiber laser module has built-in very effective relative intensity noise (RIN) suppression technology, which reduces the relaxation oscillation peak value of the single frequency fiber laser to the same level as the semiconductor laser, drops below -145dBc / Hz. The perfect combination highlights the unmatched performance of CoWIND high power continuous single frequency fiber lasers with low phase noise and low relative intensity noise (RIN). It is an ideal choice for continuous working coherent Doppler wind LiDAR.
