色散介质中无衍射无色散脉冲光束传输

Diffraction-free and dispersion-free pulsed beam propagation in dispersive media

Miguel A. Porras

摘要:

在自由空间中传播的脉冲贝塞尔光束经历类似于脉冲传播中的反常色散的衍射效应。然后,它示出,在正常色散材料中的脉冲贝塞尔光束可以保持衍射和色散自由由于相互抵消的衍射和群速度色散。用于局部传输的贝塞尔横向分布的大小由材料在脉冲载波频率下的色散特性确定。

英文摘要:

Pulsed Bessel beams of light propagating in free-space experience diffraction effects that resemble those of anomalous dispersion on pulse propagation. It is then shown that a pulsed Bessel beam in a normally dispersive material can remain diffraction- and dispersion-free due to mutual cancellation of diffraction and group velocity dispersion. The size of the Bessel transversal profile for localized transmission is determined by the dispersive properties of the material at the pulse carrier frequency.
