Optimization of Wide-Spectral Mode-Locking Fiber Laser Carriers in Free Space Optical Communication

We experimentally demonstrate an optimization of wide-spectral mode-locking fiber laser carriers by the introduction of continuous light stable pulse scheme with fiber dispersion management. The bandwidth of the optimized supercontinuum and the fluctuation between pulses have been significantly improved, and the fluctuation between pulses has been reduced by nearly 60%. After 1km of simulated atmospheric transmission, it is found that the optimized eye diagram has obvious eye opening. The signal to noise ratio increased by 6.84dB. And this optimization scheme is easy to integrate into the communication light source. It can be an adaptive scheme for free space optical communication in the foreseeable future.
