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 10.67 MHz.The pulse duration, assumed as the tit of hyperbolic secant pulse shape, is 5.82ps.We also observe the multi-pulse output of the fibre laser.
