Coherent mode locking in a two-section laser with fast gain and absorber

R Arkhipov, O Diachkova, A Pakhomov, M Arkhipov… - Applied Physics B, 2024 - Springer
Coherent mode locking is based on the formation of 2 π pulses of self-induced transparency
in the absorbing medium and π pulses in the amplifying medium. In this regime it becomes …
