摘　　要：A dark pulse mode-locked laser is experimentally demonstrated using the indium tin oxide(ITO)coated Dshape fiber as a saturable absorber(SA).Using the polishing wheel technique,a D-shape single mode fiber was fabricated.A 60-nm-thick layer of ITO was deposited over the D-shape fiber using the electron beam deposition method.The SA has a saturation intensity of 40.32 MW/cm^2 and a modulation depth of 3.5%.A stable dark pulse mode-locked laser was observed at a central wavelength of 1559.4 nm with repetition rate 0.98 MHz,pulse width 370 ns and signal-to-noise ratio 61 dB.
