Optimization Design of JW20120826 Fiber Grating Laser

输出功率和斜率效率是衡量光纤激光器输出特性的两个重要的参数,它们反映了光纤激光器的光—光转换能力。利用matlab仿真工具对双包层DBR掺镱(Yb3+)激光器的结构参数对激光输出特性的影响进行了数值模拟,得出光纤长度、腔镜反射率和激光器的输出特性之间的关系,并对激光器的参数选择提出了优化说明。

Output power and slop efficiency are two important parameters of fiber laser output characteristics, which presents the light to light transfer characteristic of fiber laser. Parameters of double cladding DBR doped Yttrium laser influenced on the laser output characteristics are numerically simulated by maflab. The rela- tionship among fiber length, cavity mirrors reflectivity and laser output characteristics are obtained. And optimi- zation scheme of laser parameter selection is proposed.
