Abstract

We constructed a panda polarization-maintaining fiber model and used finite element method to study its laser damage characteristics. We find that the anti-damage performance of the optical fiber is similar to that of a straight optical fiber under a large bending radius. But when bending radius less than 20 mm, the optical fiber is easy to be damaged, so it is not suitable for working with bend radius less than 20 mm. When studying the relation between the damage and mode number, we find that the higher-order mode is easily disordered and the fundamental mode is more stable. In addition, although the fiber is asymmetric, the damage performance of the optical fiber does not change with the bending directions.
