双镜式立体环形谐振腔是一个典型的非对称系统,为研究其像散特性,进行系统等效处理,得到4×4的系统光线变换矩阵,并利用分块矩阵的特征值性质求解得出系统像散,得到了在不同结构参数情况下的像散曲线。计算结果表明,该系统不是无像散系统,但在不同的结构参数下,像散值有大有小,且存在像散病态区域,因此可以通过合理选择结构参数来控制系统像散。这一结果也可为谐振腔的进一步研究与发展提供理论依据。
In order to study its astigmatism characteristics, a two-mirror three-dimensional ring resonator is a typical asymmetric system, and a 4 × 4 system light ray transformation matrix is obtained. The eigenvalue of the block matrix is used to solve the problem. Astigmatism system, obtained in the case of different structural parameters of astigmatism curve. The calculated results show that the system is not an astigmatic system, but the astigmatism values vary greatly with different structural parameters, and there are asymptotic areas of astigmatism. Therefore, the system astigmatism can be controlled by reasonable choice of structural parameters. This result can also provide theoretical basis for the further research and development of resonant cavity.
