Femtosecond lasers have extremely high application value in both academic and industrial fields. Accurate and rapid characterization, as well as precise control of femtosecond lasers, hold vital position in their diverse applications. Conventional characterization methods for femtosecond pulses rely on nonlinearities thereby involving complex optical setups. The control over femtosecond pulses often relies on open-loop manual tuning, where the stable optimal control is not guaranteed. As a result, the application of femtosecond lasers is greatly limited. In recent years, the emergence of intelligent technologies has provided a new paradigm for femtosecond laser research. Through introducing intelligent technologies properly, the single-shot full-field characterization over the low-energy, high-repetition-rate femtosecond pulse train and the on-demand intelligent control over femtosecond pulses can be expected in the future.
