Stress-Induced Refractive Index Changes in Laser Fibers and Preforms

Stress-Induced Refractive Index Changes in Laser Fibers and Preforms

Refractive index profile of the core is a key design parameter in fiber lasers and amplifiers. During manufacturing, the initial information of the index profile is obtained from the preform, while ultimately the performance is defined by the index profile of the fiber. Depending on stresses and dif...
