Abstract

An Er(3+):Yb(3+):LuAl(3)(BO(3))(4) crystal doped with 24.1 at.% Yb(3+) and 1.1 at.% Er(3+) ions was grown by the flux method. The polarized spectroscopic properties related to the operation of 1.5-1.6 microm laser of the crystal were evaluated at room temperature. The laser properties of a 0.7-mm-thick, c-cut crystal were investigated in diode-end-pumped hemispherical and plano-plano cavities, respectively. Compared with those of Er(3+):Yb(3+):YAl(3)(BO(3))(4) crystal obtained under similar experimental conditions, higher maximum output peak power, higher slope efficiency, and lower threshold were achieved in the Er(3+):Yb(3+):LuAl(3)(BO(3))(4) crystal.

摘要

采用助熔剂法生长了掺杂24.1原子% Yb(3+)和1.1原子% Er(3+)离子的Er(3+):Yb(3+):LuAl(3)(BO(3))(4)晶体。在室温下评估了与该晶体1.5 - 1.6微米激光运转相关的偏振光谱特性。分别在二极管端面泵浦的半球形和平平腔中研究了厚度为0.7毫米的c切割晶体的激光特性。与在类似实验条件下获得的Er(3+):Yb(3+):YAl(3)(BO(3))(4)晶体相比，Er(3+):Yb(3+):LuAl(3)(BO(3))(4)晶体实现了更高的最大输出峰值功率、更高的斜率效率和更低的阈值。
