摘　　要：基于近年来王顺金提出的处理螺旋光纤中激光 (光子 )传播时的螺旋性变化的理论方法和所得结果 ,分析了激光 (光子 )在反射后螺旋性 (左旋与右旋 )互换这一实验事实 ,发现激光 (光子 )反射的瞬息过程会产生一个极高的激光束回转频率 ,它与激光园偏振 (光子自旋 )发生科式惯性力耦合 ,进而改变激光 (光子 )的螺旋性 .还发现当激光束回转频率达到极大时 ,将发生激光 (光子 )螺旋性 (左旋与右旋 )互换 .讨论了激光反射后螺旋性互换的信息论含义及其应用 .The experimental phenomenon the helicity inversion of laser (photons) during reflection has been explained based on the quantum theory of the laser (photons) propagation through an optical helix. It is found that the instant process of the laser(photons) reflection on a mirror will produce an extremely high rotation frequency of the wave vector. The coriolis coupling between the spin of the photon and the rotation of the wave vector is the dynamical factor which dominates the process and causes helicity inversion. The implication of the helicity inversion in information theory is also discussed.
