Description
A high-power Yb:YAG thin-disc laser with radial or azimuthal polarization incorporating an intracavity
S-waveplate is reported. Depending on the rotational angle of the S-waveplate placed in the cavity, a
Yb:YAG thin-disc laser yields 10.8 W and 10.2 W of continuous-wave outputs with radial and azimuthal
polarization for an incident pump power of 131 W, corresponding to slope efficiencies of 22.9% and
23.7%, respectively. The output characteristics for each polarization state were investigated in detail by
analyzing the insertion loss and the mode overlap efficiency due to the S-waveplate. Further prospects
for power scaling will be discussed.
