Experimental Setup

Caption

The intelligent mode-locking fiber laser with an embedded time-stretch-assisted real-time pulse controller (TSRPC). The electric polarization controller (EPC) and the polarizer together produce artificially saturated absorption in nonlinear polarization evolution (NPE)-based mode locking. Part of the output power is sent to the measurement system for characterization, and the rest is used for feedback. The TSRPC consists of a dispersion compensation fiber (DCF) to complete the temporal-spectral mapping, a photodiode (PD), and a genetic algorithm-based intelligent real-time optimizer.
