无衍射光束概念及在强激光技术中潜在应用的分析

ANALYZING THE CONCEPT OF DIFFRACTION-FREE BEAMS AND THEIR POTENTIAL APPLICATIONS TO HIGH-POWER LASER TECHNOLOGIES

对近年来引起广泛研究兴趣和热烈争议的无衍射光束和相关的物理概念、产生方法和传输特性，以及在强激光技术中应用的可能性等问题，作了详细的物理分析，以期引起讨论。

In recent years extensive investigations and comments have been devoted to the diffraction-free beams. In this paper, the related physical coneepts,production methods and propagation properties of difftaction-free beams,and their potential a pplications to high-power las er technologies are analyzed phys ically in detail,so as to expect a further discussion.
