Abstract
A radially polarized thin disk laser comprises a pumping source (), a collimating lens (), a focusing lens (), a laser gain medium (), a heat dissipating medium (), a Brewster biaxial cone (), and an output lens () which are arranged in sequence along the laser light path. The Brewster biaxial cone () comprises two opposite cones and a cylinder connecting the two cones. The angles between the conical surfaces (S,S) and bottom surfaces of the cones are the Brewster angle. The laser gain medium () is bonded to the heat dissipating medium (). A laser sub-resonator is formed between the laser gain medium () and the output lens (). After passing through the collimating lens () and the focusing lens (), the pumping laser beam emitted from the pumping source () is focused on the laser gain medium (), then the generated photons resonate in the laser sub-resonator and finally a radially polarized laser beam is outputted from the output lens ().
