RADIAL POLARIZATION THIN-DISK LASER

摘要

A radial polarization thin-disk laser (100) comprises a pumping source (10), a collimation lens (20), a focusing lens (30), a laser gain medium (50), a Brewster axial cone (60), and an output lens (70) sequentially arranged along a laser light path. An included angle between the conical surface and the bottom surface of the Brewster axial cone (60) is a Brewster angle. The laser gain medium (50) is bonded with the bottom surface. The laser gain medium (50) and the output lens (70) form a laser harmonic oscillator cavity (80). Laser light emitted by the pumping source (10) passes through the collimation lens (20) and the focusing lens (30), and then is focused to the laser gain medium (50). Generated photons oscillate in the laser harmonic oscillator cavity (80), and a radial polarization laser beam (90) is finally output from the output lens (70).
