Mode-locked lasers produce ultrashort pulses at high frequencies, but generally with low pulse energies (or with ultra-long cavity lengths to increase pulse energy). Q-switched lasers typically have lower repetition rates, but higher energies and wider pulses. Although combining both effects produces high-energy, higher-repetition-rate, shorter pulses, this doubly active performance had not been demonstrated for a fiber laser--until now. Researchers at Universidad de Valencia are the first to demonstrate a Q-switched, mode-locked (QML) fiber laser, that even uses all-fiber inline components.
