926 nm Yb-doped fiber femtosecond laser system for two-photon ...
short pulse fiber lasers owing to its large gain efficiency and broad gain bandwidth.4) Matured Yb-doped fiber femtose-cond lasers mainly focused on 1030nm and 1064nm.13,14) Recently, Yb-doped fiber femtosecond lasers that can operate from 825nm to 1210nm have been demonstrated.15) The narrowband Yb-fiber laser generated the broadband tunable
