摘要

光纤激光器相较于传统激光器拥有巨大优势。为了研制具有更佳输出特性的光纤激光器

文章提出一种全固态掺镱正方晶格光子晶体光纤

利用全矢量有限元法对光纤结构和特性进行模拟。通过规划缺陷位置、优化掺入氧化硼的介质柱尺寸

使该光纤在1.06μm处基模模场面积达到4 405μm2

可满足单模传输条件并且具有低弯曲损耗特性

在弯曲半径!8cm时仍可以单模传输。该光纤可以在高功率光纤激光器中作为增益光纤使用。

Abstract

Fiber lasers have huge advantages compared with the traditional lasers.This paper proposes a novel all-solid squarelattice Yb3+-doped Photonic Crystal Fiber（PCF）for the development of fiber lasers with still better output characteristics and simulates its structure and properties by using the Finite Element Method（FEM）.By designing defect positions and optimizing the sizes of B2O3-doped rods

it enables the Mode Field Area（MFA）of the fundamental mode of this fiber to reach 4 405μm2 at 1.06μm and satisfy the conditions for single-mode transmissions and low bending loss properties at the same time

i.e.maintaining single-mode transmissions when the bending radius is larger than 8cm.This PCF can be used as a gain fiber in high power fiber lasers.
