  1. In the experiment, we use the he - ne laser and the semiconductor laser as the source, record the bessel beam patterns behind the axicon by using a digital camera and a microscope, measure the radius of the bessel beam central spot by film - scanning and measure the effect of both the radius of the aperture and the open angle of the axicon on the maximum non - diffraction distance. the experiments show that a specific propagating range has constant power and the beam has a bessel - like distribution in this range. the results agree with the beam corresponding to a diffraction free beam

    同時我們還採用片掃描的方法測量了無衍射光束的中光斑尺寸,測量了不同光闌孔徑和不同稜角情況下的最大無衍射距離和傳播附近橫截內微小光孔中的光強,實驗結果顯示當激光光束經過棱錐轉換後有一段距離功率變化很小,且分佈近似貝塞爾分佈,符合無衍射光束的特性;經過聚焦后,呈現三維分佈中空的光束bottlebeam ,實驗結果與理論分析基本吻合。
