Abstract:
We report an approach to the control of the longitudinal mode structure in erbium-doped fiber lasers that uses saturable absorbers and the spatial hole-burning effect in the laser cavity. Two- and three-mode fiber lasers are successfully demonstrated, and the laser output properties are compared with theoretical calculations.
