ABSTRACT:
A passively mode-locked, figure-eight laser is formed of all normal dispersion fiber, eliminating the need for using anomalous dispersion fiber. The fiber is selected to be polarization maintaining, with the remaining components of the laser (couplers, isolator, gain fiber) also formed as polarization maintaining elements. In one embodiment, a section of Yb-doped fiber is used as the gain element. An external modulation component (amplitude or phase) is preferably used to initiate the passive mode locking.
