稳定腔激光模式理论的再研究

Study on the transverse modes in stable optical resonators

为了完善和发展激光器谐振腔的模式理论,要求对稳定腔激光器模式理论进行再研究。采用一种解析方法对稳定腔激光模式的光场分布进行了求解,得出稳定腔激光模行波光场分布的一种解析表达式,并用图视的方法给出了一台平-凹谐振腔Nd:YAG激光器的几个低阶模光强分布的计算结果,以此深化了对稳定谐振腔激光模式理论的认识。

In order to develop laser modes in stable resonators, an analytical method was adopted to resolve the field distribution of the laser modes in stable optical resonators. The expressions for the laser modes were derived after seeking simple solutions to Maxwell＇ s equations. The plots of the field intensity distribution corresponding to some laser modes in plan-concave Nd：YAG laser were shown. The theory of laser modes in stable resonators was enhanced.
