Abstract

The beam-quality factor M(2) for the fundamental LP01 mode of a step-index fiber is calculated in the presence of gain, in a closed form, as a function of the complex generalized V number. It is shown that the M(2) value of a single-mode gain-guided fiber laser can be arbitrarily large. The results are important for the interpretation of the beam-quality measurements in recent experiments on single-mode gain-guided fiber lasers.

摘要

在存在增益的情况下，以封闭形式计算了阶跃折射率光纤基本 LP01 模式的光束质量因子 M(2)，作为复广义 V 数的函数。结果表明，单模增益引导光纤激光器的 M(2)值可以任意大。这些结果对于解释最近单模增益引导光纤激光器实验中的光束质量测量结果非常重要。
