计算了轴棱锥焦散面上的激光辐射强度。计算被用来开发优化的方法，通过匹配的轴棱锥聚焦元件和初始激光束横截面中的强度分布的轮廓的聚焦。结果被用来确定连续的激光火花的尺寸获得轴棱锥聚焦的激光辐射在气体中。
Calculations are made of the laser radiation intensity in the caustic of an axicon. Calculations are used to develop methods for optimizing the focusing by matching the profiles of axicon focusing elements and the intensity distribution in the initial laser beam cross section. The results are used to determine the dimensions of continuous laser sparks obtained by axicon focusing of laser radiation in a gas.
