The formulas of mode conversion are derived and effects of optical beam power, initialbeam width radius and inverse of the radius of curvature of the wave front on the mode conversion are analysed.
导出模式变换公式，分析了光束功率、光束初始的束宽半径和波前曲率半径的倒数对模式变换的影响。

My initial ideas focused on laser beam-type duels between friends in front of the camera.
我最初的想法是让朋友们在摄像机前面进行星球大战那样的激光剑格斗。
