摘要
3µm激光处于分子指纹区,在医疗外科、气体检测、军事应用等领域都有重要的应用价值。Er^(3+)∶ZBLAN光纤激光器具有效率高、可集成的优点,是3µm激光的主要输出方式。本文从铒离子跃迁产生3µm激光出发,围绕Er^(3+)∶ZBLAN光纤激光器,介绍了3µm激光产生的结构原理及能级系统,总结了实现该波段高功率连续输出和脉冲输出的技术方案和研究进展,重点介绍了基于不同材料可饱和吸收体的调Q和锁模激光器实验研究,并对目前实现3µm波段高功率输出需要解决的问题进行了分析,最后对Er^(3+)∶ZBLAN激光器的发展方向进行了展望。
3µm laser is located in the molecular fingerprint region and has important application value in fields such as medical surgery,gas detection,and military applications.Er^(3+)∶ZBLAN fiber laser has the advantages of high efficiency and integration,making it the main output mode of 3µm laser.Starting from the generation of 3µm laser by erbium ion transition,this article introduces the structural principle and energy level system of 3µm laser genera-tion,summarizes the technical solutions and research progress for achieving high-power continuous output and pulse output in this band,with a focus on the experimental research of Q-switched and mode-locked lasers based on satura-ble absorbers of different materials.And analysis of the problems is solved in order to achieve high power output in the 3µm band.Finally,the development direction of Er^(3+)∶ZBLAN lasers is prospected.
