对由两个端面镜和两个直边镜组成的对称准体育场半导体激光器的谐振腔本征模进行了理论研究。我们得到了典型的谐振腔条件下，即，一个同心和近同心谐振腔条件，共焦谐振腔条件，几何不稳定的谐振腔条件下的谐振腔本征模。我们采用了扩展的Fox-Li模式计算方法，该方法考虑了侧壁反射镜的全内反射效应。获得了独特的谐振腔本征模。在同心腔和近同心腔条件下，不仅得到了厄米-高斯模，而且得到了环轨模。在非稳腔条件下，谐振腔本征模的衍射损耗显著地依赖于波长。在最小衍射损耗的波长处，高度定向的光束在谐振器内沿着封闭的重复轨迹传播。
Resonator eigenmodes in symmetric quasi-stadium laser diodes consisting of two curved end-mirrors and two straight side-wall mirrors are theoretically studied. We obtained the resonator eigenmodes under typical resonator conditions, namely, a concentric and a near-concentric resonator conditions, a confocal resonator condition, and a geometrically unstable resonator condition. We used the extended Fox-Li mode calculation method which includes the effect of the total internal reflection at the side-wall mirrors. Unique resonator eigenmodes are obtained. Under the concentric and the near-concentric resonator conditions, not only the Hermite-Gaussian modes but also ring-trajectory modes are obtained. Under the unstable resonator condition, the diffraction loss of the resonator eigenmode significantly depends on the wavelength. At the wavelength of minimum diffraction loss, the highly directional beams propagate along the closed repetitive trajectories inside the resonator.
