Claim:
1. A radial polarization disk laser, comprising: a pump source, a collimator lens, a focusing lens, a laser gain medium, a heat dissipating medium, a Brewster double axial cone, and a output lens, which are sequentially arranged along a laser light path, wherein the Brewster double axial cone comprises two cones facing each other and a cylinder connecting the two cones, an angle formed between a conical surface and a bottom surface of the cone is a Brewster's angle; the laser gain medium is bonded to the heat dissipating medium; the laser gain medium and the output lens form a laser harmonic oscillator cavity therebetween; wherein pumped laser emitted from the pump source passes through the collimator lens and the focusing lens, is then focused on the laser gain medium, and generated photons oscillate in the laser harmonic oscillator cavity, and then a radially polarized laser beam is finally output by the output lens.
