研究了Yb:KLu(WO4)2晶体对非偏振抽运光的吸收以及连续波激光振荡性质.晶体结构的低对称性导致晶体光谱呈强烈各向异性,最强的吸收和发射都发生在平行于Nm主轴的偏振方向上.Ng切向晶体具有最高的非偏振抽运光吸收效率和最大的激光功率产生潜力,2mm长的晶体产生的最高连续波输出功率为11W,相对于吸收抽运功率,光—光转换效率为68%,而斜率效率则达80%.
The absorption of unpolarized pumping light and the continuous-wave laser oscillation properties of Yb: KLu (WO4) 2 crystal were studied. The low symmetry of the crystal structure led to the strong anisotropy of the crystal spectrum. The strongest absorption and emission occurred in parallel The Ng tangential crystal has the highest non-polarized pumping light absorption efficiency and maximum laser power production potential in the polarization direction of the Nm main axis, and the maximum continuous wave output power produced by a 2 mm long crystal is 11 W, which corresponds to the absorption pumping power , The light-to-light conversion efficiency is 68%, and the slope efficiency is up to 80%.
