Design of Pumped Er3+:Yb3+ Codoped All-solid-state Laser

摘要:

对LD泵浦Er^3＋∶YB^3＋共掺全固态激光器进行了整体设计，利用矩阵光学方法推导了高斯光束经耦合系统聚焦后束腰宽度和像距的计算公式。考虑激光棒的热透镜效应，对有源平平腔、平凹腔进行了数值计算，分析了谐振腔的稳定性。最后，根据激光谐振条件，确定了激光输出镜及滤光片的镀膜方案，为最终获得高效率、稳定的激光输出提供了理论依据。

Abstract:

By using the method of matrix optics, the formula was deduced for computing the beamwidth and image distance of the Gauss beam after focusing by coupling system. Considering the thermal-lens effect, numerical simulations were performed on the active plano-concave cavity. Finally, according to the conditions of laser resonator, the coating program for the output mirror and filterwas confirmed.
