Two types of ultrafast mode-locking operations from an Er-doped fiber laser based on germanene nanosheets

Two types of ultrafast mode-locking operations from an Er-doped fiber laser based on germanene nanosheets

Abstract As a member of Xenes family, germanene has excellent nonlinear saturable absorption characteristics. In this work, we prepared germanene nanosheets by liquid phase exfoliation and measured their saturation intensity as 0.6 GW/cm2 with a modulation depth of 8%. Then, conventional solitons wi...
