摘要：

We propose and demonstrate a strictly all-fiber erbium doped passively mode-locked figure-eight fiber laser (EDFL) In the laser structure we use the nonlinear optical loop mirror combination with a variable ratio coupler (VRC-NOLM) to achieve mode-locking Due to the nonlinear effect in the nonlinear fiber stable self-starting pulse is obtained In order to reduce the repetition of pulse a segment of nonlinear fiber (NLF) has been incorporated into the VRC-NOLM The laser generates stable rectangular pulses with a low repetition rate (kilohertz magnitude) by extending the length of the cavity Furthermore the output pulse width of the fiber laser can be varied by changing the coupler ratio of the variable ratio coupler (C) 2010 Published by Elsevier Ltd
