我们观察到准体育场激光二极管的复杂本征模激射与非稳腔组成的两个弯曲的端镜服从非稳腔条件和两个直的侧壁镜。该激光器是通过将反应离子刻蚀技术应用于分子束外延生长的梯度折射率分别限制异质结构单量子阱GaAs/AlGaAs结构而制成的。远场图表明，激光模式对应于由扩展的Fox-Li方法数值计算得到的复杂的最低损耗模式。
We have observed lasing in a complicated eigenmode of a quasi-stadium laser diode with an unstable resonator consisting of two curved end mirrors obeying an unstable resonator condition and two straight sidewall mirrors. The laser was fabricated by application of a reactive-ion-etching technique to a molecular beam epitaxy-grown graded-index separate-confinement heterostructure single-quantum-well GaAs/AlGaAs structure. The far-field pattern shows that the lasing mode corresponds to the complicated lowest-loss mode obtained numerically by an extended Fox-Li method.
