This phenomenon, observed in 1450 nm mode-locked bismuth-doped fiber laser, shows the distinct feature of the multiple pulse regime, which appears as a stationary pulse group whose length can be spread over the whole cavity length by variation of the pump power and polarization. Pulse positioning within the ensemble depends on the saturation fluence and the relatively fast recovery dynamics of bismuth fiber.Scientific reports7044https://www.ebi.ac.uk/biostudies/studies/S-EPMC5382671biostudies-literatureEffect of absorption recovery in bismuth-doped silica glass at 1450 nm on soliton grouping in fiber laser.PMC5382671Dianov EMMelkumov MAGumenyuk ROkhotnikov OGKhopin VF46falseEffect of absorption recovery in bismuth-doped silica glass at 1450 nm on soliton grouping in fiber laser.Saturable absorption in bismuth-doped glasses was found to have a noticeable influence on soliton interaction and group formation.
