▎ 摘　　要

A single-wavelength compact diode-pumped solid-state laser based on a single-mode waveguide with a diameter of 20 mu m and graphene saturable absorber is presented in this work. The total reflection coefficient of the intracavity interferometer has a significant effect on the level of intracavity losses. By accurate controlling the intracavity losses a stable continuous wave passive mode-locking at wavelength of 1064 nm with a pulse repetition rate of 9.5 GHz was obtained.
