摘要

摘要:我们提出了一个非常简单的“玩具模型”，它允许人们恢复导致具有不稳定谐振腔的激光器中过量量子噪声和过量线宽的基本数学和物理特征。在一致的量子力学描述中，多余的噪声因子(彼得曼因子)在物理上归因于腔本征模之间的损耗诱导耦合。

A simple quantum picture for the Petermann excess noise factor

Abstract:We present a very simple “toy model” that allows one to recover the essential mathematical and physical features that lead to excess quantum noise and excess linewidth in lasers with unstable resonators. In a consistent quantum mechanical description, the excess noise factor (Petermann factor) is physically attributed to loss-induced coupling between the cavity eigenmodes.
