摘要
采用自行研制的内包层为矩形的掺Yb3+双包层石英光纤,以透射率不同的一组二向色镜为后腔镜构成了双包层光纤激光器。实验证明:后腔镜具有较高透射率为佳;后腔镜可以实现对激光波长的控制;激光斜率效率与后腔镜透射率之间的关系符合指数变化规律,在本实验的条件下,斜率效率的最大值约60%。
Abstract
By using Yb3+ doped double clad fiber with rectangular inner cladding and a set of back cavity mirrors with different transmission ratio, the double clad fiber lasers are constructed. It is found that the back cavity mirror with a higher transmission ratio is better, and the laser wavelength can be controlled by a back cavity. The relationship between slope efficiency and transmission ratio is in accordance with exponential function and the maximum slope efficiency is about 60%.
