  1. Chapter 2 : the basics equations and the complex analytical signal theory are introduced

    第二章:首先介紹了porras提出的超短脈沖光束表達式和復解析信號理論。
  2. In particular, based on the complex analytical signal theory, the solutions for the components of a pulsed gaussian - like beam in rectangular symmetry are derived and compared with those derived from slowly - varying - envelop - approximations ( svea )

    本部分給出了時間波形為gauss 、 hyperbolicsecant和lorentz的脈沖光束奇異性的計算模擬,並給出了解決這些奇異性的復解析信號( complexanalyticalsignal )解。
  3. But the complex analytical signal ( cas ) theory can erase this spatial sigu - larity. in this section, gauss, hyperbolic and lorentz pulsed gaussian beam have been derived and compared svea and cas solution by numerical simulatio n. in section 3, by using fourier transform technique and applying the paraxial approximation in frequency domain, we derive an integral solution for the transverse and longitudinal components of the light field propagating in free space

    接著,考慮了幾種特殊的脈沖gauss光束( pulsedgaussianbeam ) ,結果顯示,在此情況下緩變包絡近似( slowly - varyingenvelopeapproximation )理論已不再有效,其失效的原因是,該理論導致了脈沖光束解的空間奇異性,並使脈沖光束不再具有符合物理意義的光束行為,而通過復解析信號的分析方法可以消除這種空間奇異性。
