随时间衍射的高斯光束

Gaussian beams diffracting in time

Miguel A. Porras

摘要:

我们展示了如何将任何单色近轴光束的数学表达式转换为脉冲光束的衍射从轴向切换到其时间结构的表达式。我们用时间衍射高斯光束来描述这种变换。讨论了所得到的无衍射波具有物理意义的条件。

英文摘要:

We show how to transform the mathematical expression of any monochromatic paraxial light beam into the expression of a pulsed beam whose diffraction is switched from the axial direction to its temporal structure. We exemplify this transformation with time-diffracting Gaussian beams. The conditions for the obtained diffraction-free wave to be physically meaningful are discussed.
