实验研究了二极管激光器抽运的国产Yb∶YAG陶瓷的高效率连续激光输出和波长调谐输出特性。比较了不同掺杂原子数分数(1%、2%、5%、10%、15%)和不同厚度(3、6 mm)的激光陶瓷的输出激光性质。当吸收抽运功率为6.3 W时,在3 mm厚15%掺杂样品中得到了2.4 W的连续激光输出功率,斜效率为47%。在谐振腔内插入三棱镜进行波长调谐,实验上得到的最宽波长调谐范围为1017~1095 nm。实验结果表明高质量的Yb∶YAG陶瓷在高功率全固态超短脉冲产生和放大中具有重要的应用。 Experimental study of the diode laser pumped domestic Yb:YAG ceramic high-efficiency continuous laser output and wavelength tuning output characteristics. The output laser properties of laser ceramics with different doping atomic numbers (1%, 2%, 5%, 10%, 15%) and different thickness (3,6 mm) were compared. When the absorbed pumping power was 6.3 W, a continuous laser output of 2.4 W was obtained in a 3 mm thick 15% doped sample with a ramp efficiency of 47%. Triangular prism is inserted into the cavity to tune the wavelength. The tuning range of the widest wavelength experimentally is 1017 ~ 1095 nm. The experimental results show that high quality Yb: YAG ceramics have important applications in the generation and amplification of high power all solid state ultrashort pulses.
