傍轴光束截面的内能是一个不变量
On the invariable property of internal energy of paraxial beam cross-section
摘要
本文从描写光束传输的流体模型中建立了内能概念.证明,对于任何一个在真空中稳态传输的傍轴光束,光束截面的内能与截面的位置无关,即在传输过程中,内能是一个不变量.
Abstract
A physical concept called internal energy have been set up from the hydrodynamic model describing the light beam transmission[1]. In this paper authors expect to demonstrate that for any stable paraxial light beam transmitting in vacuum, the internal energy of the light beam is not dependent on the position of the beam cross-section. In other words, in the cause of transmitting, the internal energy is a constant.
