多通模激光器的主要性质和应用前景引言大孔径激光谐振腔特性的最佳化问题是研究谐振腔中激发能不引起附加能量损耗并保证在输出端获得高辐射质量的振荡模式。虽然该课题有大量文献发表，但缺乏有关所谓多通模（多束模）的振荡特点和相互作用机制的信息［１－３］。这种模... Main properties and application prospect of multipass mode lasers Introduction The optimization of the characteristics of the large aperture laser resonator is to study the oscillation mode in which the excitation energy in the resonator does not cause additional energy loss and ensure high radiation quality at the output end. Although a large number of papers have been published on this topic, there is a lack of information on the oscillation characteristics and interaction mechanisms of the so-called multi-mode (multi-beam mode) [1-3]. This model ...
