It is found that they are the same in the neighbourhood of z-axis for narrowband pulses, but in the case of broadband pulses, singularities emerge near z-axis for pulsed beams obtained by using complex amplitude envelope representation and only complex ana.
数值结果表明脉冲光束为窄带时,在传输方向轴中心的一定范围内两种解是一致的,而对于宽带脉冲光束,复振幅包络解在轴中心较近的距离即表现出奇异性,复解析信号解才是符合物理意义的表示式。
