We propose and demonstrate a mode-locked all-fiber cylindrical-vector beam (CVB) laser with high efficiency and tunable repetition rate. By controlling the intra-cavity polarization states, both azimuthally polarized and radially polarized beams are selectively obtained under harmonic mode-locking (HML) states.
