The relation between the spatial singularity of ultrashort pulsed beams and the spectrum 超短脈沖光束空間奇異性與頻譜的關系
The propagation of such kind ultrashort pulsed beams has attracted much interest 這類超短脈沖光束的傳輸變換引起了廣泛的研究興趣。
Then the influence of the spectrum property on the non - paraxial property of the pulsed beam is discussed 并對脈沖頻譜特性對其非傍軸特性的影響進行了討論。
