Abstract

We report on the generation of kW-class, continuous-wave, radially polarized laser radiation in an Yb:LuAG thin-disk laser (TDL). Output powers of up to 980 W were achieved with optical efficiency of 50.5% with respect to the incident pump power of the TDL. The degree of radial polarization was measured to be 95.5% at maximum output power. This was achieved by the integration of a new generation of broadband, large-area grating-waveguide mirror with unprecedented high polarization discrimination as the end-mirror in the TDL resonator.

摘要

我们报道了在镱掺杂的钇镥铝石榴石（Yb:LuAG）薄片激光器（TDL）中产生千瓦级连续波径向偏振激光辐射的情况。相对于TDL的入射泵浦功率，输出功率高达980瓦，光学效率为50.5%。在最大输出功率下，径向偏振度测得为95.5%。这是通过在TDL谐振器中集成新一代宽带、大面积光栅波导镜实现的，该镜具有前所未有的高偏振鉴别能力，作为端镜使用。
