The three-dimensional field distribution of the diffractive cavity mode structure in a passive, open, unstable resonator is presented as a function of the equivalent Fresnel number of the cavity. The qualitative structure of this intracavity field distribution, including the central intensity core (or oscillator filament), is characterized in terms of the Fresnel zone structure that is defined over the cavity feedback aperture. Previous related research is reviewed.
给出了无源、开放、非稳谐振腔中衍射腔模结构的三维场分布,它是腔的等效菲涅耳数的函数。腔内场分布的定性结构,包括中心强度核(或振荡细丝),是根据在腔反馈孔径上定义的菲涅耳区结构来表征的。回顾了先前的相关研究。
