Researchers in China led by Lilin Yi at Shanghai Jiao Tong University developed apparatus and software algorithms allowing automatic 'intelligent control' over the femtosecond pulses generated by mode-locked fiber lasers. The system can manipulate key aspects of the wavelength range and composition of the pulses—technically their 'spectral width' and 'spectral shape'—more effectively than previously possible. The procedure also yields new technical insights into the factors determining the nature of femtosecond pulses generation.
