光学周期 meaning in Chinese

optical cycle

Porras and fu et al proposed that slowly varying envelope approximation and the complex amplitude envelope do n ' t fit anymore for the ultrashort pulsed beam shorter than or even near to one oscillation optical period , because they lead to a spatial singularity
结果表明，对于脉冲宽度较长(相对于一个光学周期)的超短无啁啾脉冲光束可以使用缓变包络近似和复振幅包络表达式。
Chapter 3 : we find a family of solutions of the paraxial wave equation that represents ultrashort pulsed light beams propagation in free space . these pulsed beams have an arbitrary temporal form and a nearly elegant hermite - gaussian cross section , which pulsed beams we call the ultralshort pulsed elegant hermite - gaussian beams
此脉冲光束解的每个频率分量都是eleganthermite - gaussain光束，时间脉冲的形状是任意的，具有相同的衍射距离参数，并且可以描述短于一个光学周期的超短脉冲。
