Abstract

We report a high power Yb:YAG thin disk laser with cylindrical vector polarization incorporating an intracavity S-waveplate. By adjusting the angle of the S-waveplate in the resonator, we could select a cylindrical vector polarization state of the laser output, radial or azimuthal polarization, in the Yb:YAG thin disk laser resonator. The laser yielded ⪆10 W of both radial or azimuthal polarized output for incident pump power of 131 W in continuous-wave mode of operation, corresponding to the slope efficiency of ⪆18%. Output characteristics will be discussed in detail.
