Effect of absorption recovery in bismuth-doped silica glass at 1450 nm on soliton grouping in fiber laser

Abstract

Saturable absorption in bismuth-doped glasses was found to have a noticeable influence on soliton interaction and group formation. 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… (More)
