摘　　要：A self-starting, passively mode-locked all-fibre ring laser based on the homemade Er^3＋/Yb^3＋ 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.A self-starting, passively mode-locked all-fibre ring laser based on the homemade Er^3＋/Yb^3＋ codoped phosphate glass fibre is reported.
