Self-Starting Passively Mode-Locked Er3+/Yb3+ Codoped Phosphate Glass All-Fibre Ring Laser
-
Abstract
A self-starting, passively mode-locked all-fibre ring laser based on the homemade Er3+/Yb3+ codoped phosphate glass fibre is reported. Dual-pump sources were used to achieve the mode-locked operation in the experiment. The fundamental mode-locked pulse repetition rate is 10.67MHz. The pulse duration, assumed as the fit of hyperbolic secant pulse shape, is 5.82ps. We also observe the multi-pulse output of the fibre laser.
