Abstract

There is a new issue that needs to be explored which concerns the spatial behavior of optical systems and lasers in particular: are lasers able to display the type of complex spatial structures such as one finds under fully developed turbulence conditions in hydrodynamic systems? Turbulence involves increasing complexity not only in time but also in space; one could argue that, just as dynamical chaos results from the presence of at least a few competing frequencies in a nonlinear system, spatial complexity may be obtained when competing spatial structures play a relevant role in the evolution of a dynamical system.
激光中的对称破缺和缺陷介导的湍流
有一个新的问题需要探索,特别是关于光学系统和激光器的空间行为:激光器是否能够显示复杂的空间结构类型,例如在流体动力系统中完全发展的湍流条件下发现的类型?湍流不仅在时间上而且在空间上都日益复杂;有人可能会争辩说,正如动态混沌是由非线性系统中至少几个竞争频率的存在造成的,当竞争空间结构在动力系统的演化中发挥相关作用时,可能会获得空间复杂性。
