摘要

以光纤耦合半导体激光器作为泵浦源

5 mm长的铯蒸气池作为激光增益介质

开展了端面泵浦铯蒸气激光器的模式匹配实验研究。分析了泵浦光聚焦光斑半径和聚焦位置对铯激光输出性能的影响。以激光器的工作斜效率和光光效率为指标对各模式匹配参数进行了优化

同时对激光器的阈值泵浦功率进行了研究。结果表明:在一定的激光振荡模束腰下

存在最佳的泵浦光聚焦光斑半径使斜效率最大。此外

聚焦位置在蒸气池中央时有利于提高斜效率和光光效率。对阈值泵浦功率的研究显示

阈值泵浦功率随泵浦光聚焦光斑半径的减小而减小

而且当泵浦光聚焦于蒸气池前端时有利于降低阈值泵浦功率。基于以上研究

获得了一组最佳模式匹配参数

即泵浦光聚焦光斑半径为333 μm

激光振荡模束腰为167 μm

泵浦光聚焦位置位于蒸气池中央。

Abstract

By employing a fiber-coupled diode-laser as the pump source and a 5 mm long cesium vapor cell as laser media

the experiments on the mode-matching of a LD-end-pumped cesium vapor laser were investigated. The effects of the focus spot radius and the position of focused pump light on the output characteristics of cesium laser were analyzed. Then

the different mode-matching parameters were optimized to allow the slope efficiency and optical-to-optical efficiency to be maximal. Furthermore

the threshold pump power of the laser was studied. Results show that there is an optimal focused spot radius to allow the slope efficiency to be the highest when the laser resonant mode beam is constant. Moreover

it is beneficial to improve the efficiency when the focused spot position is in the center of vapor cell. The threshold pump power was also researched

which shows the power can decrease with decreasing the focus spot radius of pump light

and when the pumping light focuses on the front of the vapour cell

the pumping power can be reduced. Finally

a series of parameters were optimized at the laser mode waist of 167 μm

and they are focused spot radius of 333 μm

spot position of 2.5 mmm and the focusing position of pumping light on the center of the vapour cell.
