Numerical Analysis and Optimization of AOS for Actively Q-switched High Power Fibre Laser
Na Xiao andYu Ruan
The characteristics of an actively Q-switched rare-earth-doped high power fibre laser are presented. Based on numerical simulations, extensive analysis and optimization work on an acousto-optic switch (AOS) was done to improve the active Q-switched high power fibre laser performance. This helps to generate a stable and robust Q-switched pulse train with a good stability, tailored pulse shape and desired characteristics for appropriate applications.
