N2 - A Q-switched mode-locked Nd:GdVO4 laser with azimuthal polarization was generated using a semiconductor saturable absorber mirror. On the basis of the birefringence of the laser crystal inducing different equivalent lengths for ordinary and extraordinary rays, beams were azimuthally polarized around the edge of a stable cavity region. At a pump power of 9W, the repetition rate and width for the Q-switched envelope were 318 kHz and 0.91 μs, and the mode-locked pulse repetition rate and pulse width were 455MHz and 65 ps, respectively. The degree of polarization was controllable up to 95.4 ± 1.4%.
