摘要

本文对可用作圆盘激光器的圆盘谐振器进行了二维时域有限差分建模。结果显示了模式间距,并与一个简单的低语画廊模式模型很好地吻合。研究了直接耦合波导对模态特性的影响,观察到腔Q的大幅度降低。

FDTD Modelling of Mid Infrared Disk Lasers
This paper presents 2D FDTD modelling of a disk resonator that could be used as a disk laser. Results are shown for mode spacing and good agreement with a simple Whispering Gallery Mode model is observed. The influence of direct coupled waveguides on modal behaviour is studied and a large reduction in cavity Q is observed.
