Iteratively seeded mode-locking. [PDF]
Opt Express, 2017 Ultrashort pulsed mode-locked lasers enable research at new time-scales and revolutionary technologies from bioimaging to materials processing. In general, the performance of these lasers is determined by the degree to which the pulses of a particular resonator can be scaled in energy and pulse duration before destabilizing.

Stable coherent mode-locking based on $$\pi$$ π pulse formation in single-section lasers [PDF]
Scientific Reports, 2021 Here we consider coherent mode-locking (CML) regimes in single-section cavity lasers, taking place for pulse durations less than atomic population and phase relaxation times, which arise due to coherent Rabi oscillations of the atomic inversion ...
