摘 要: 利用二极管泵浦对掺杂原子分数为3%的Yb:LuAG陶瓷进行抽运,实现了输出波长为1 031 nm的连续激光器。实验中采用三镜折叠腔结构。当LD泵浦芯径为100 μm、晶体吸收功率为11.3 W时,获得了最高功率为2.2 W的TEM00模式连续激光输出,相应的激光斜效率为27%. Yb:LuAG陶瓷与InGaAs二极管极好的耦合性,使其成为可以应用LD泵浦的高效、高功率激光的新固体激光增益介质。
关 键 词: 光学;激光技术;Yb:LuAG陶瓷;低阈值;二极管抽运

Abstract: The diode pumped ceramic laser was demonstrated in this paper with Yb:LuAG sample which was doped with atom fraction of 3%. A stable three-folded resonator was adopted in this experiment and the obtained laser wavelength was centered at 1 031 nm. The laser performance was checked with different high brightness fiber-coupled diode lasers. The highest output power of 2.2 W with TEM00 model was obtained at a non-lasing absorbed pump power of 11.3 W when the diode laser with a core diameter of 100 μm was applied, with the corresponding slope efficiency of 27%.
