关于衍射与无衍射光束
Light Diffraction and Diffraction-free Beams
摘要
分析了衍射与无衍射光束的特点,讨论了无衍射光束的判据,指出衍射实质上是波动方程的非本征解光束在传输过程中趋于本征解光束的特点。
Abstract
Characteristics of light diffraction and diffraction free beams are analyzed. The criterion to diffraction free beams is discussed. It is pointed out that light diffraction means a non eigen solution beam of the wave equation degenerating into an eigen solution beam during propagation.
