一种输出无衍射光束的金属环状波导激光器的光场特性
Light Field Characteristics of Annular Waveguide Laser with All-metallic Materials for Generating Non-diffracting Beam
摘要
Abstract
The situation of an annular waveguide laser with all-metallic materials for generating non-diffracting beams is presented. The properties of the electromagnetic field distribution,near- and far- field and the coupling Loss of the transverse electric (TE) mode in the resonator are analyzed in detail. The formation mechanism of the non-diffracting beam is analyzed by geometrical optics, and the relevant parameters are also calculated. The intensity distribution of output beam is simulated by diffraction and interference theory. The results are basically consistent with the geometrical optics. The research shows that non-diffracting beams can be generated by this element.关键词
