Paper Abstract

A new method of using a cascaded long-period fiber grating (CA-LPFG) as the spectral filter in the ytterbium-doped mode locking in the normal dispersive regime are proposed. The CA-LPFG was fabricated in a single mode fiber at wavelength of 1064nm using a CO2 laser based system. A stable mode-locking laser output at wavelength of 1034nm was observed and measured in the normal dispersive regime. In comparison with the conventional interference filters or fiber Bragg grating filters, the CA-LPFB can provide not only an all-fiber low-loss but also a transmission mode.
