electron beam laser 中文意思是什麼
electron beam laser
解釋
電子束激光器-
The propagation of ultrashort laser pulse in air is analyzed with mechanics analogy by considering kerr effects and free electron defocusing. the equation describing the evolution of the laser spot is derived. it is shown that long distance focusing requires large initial beam and the propagation distance is very sensitive to the initial divergence angle of the laser beam
