Abstract

Pulse lasing driven by a real saturable absorber (SA) in a fibre laser cavity is conditional on modulation characteristics determined by the nonlinear material and implementation geometry of the SA. Generally, these parameters can be only preset during the SA fabrication. For instance, modulation depth of a single-wall carbon nanotube saturable absorber (SWCNT-SA) sandwiched between fibre connectors is governed by its thickness [1]. Here we demonstrate electronic control of pulse lasing regimes in an all-PM fibre laser by using an original electrochemically gated in-line SWCNT-SA. Earlier it was shown that electric gating of graphene can alter its nonlinear optical properties [2], but for SWCNT, to the best of our knowledge, there were no such studies.
