Revealing the propagation dynamic of Laguerre-Gaussian beam with two Bohm-like theories
Peng-Fei Huang, Ya Xiao, Shan-Chuan Dong +1
By employing x-Bohm theory and p-Bohm theory, we construct the position and momentum trajectories of single-mode and superposed-mode Laguerre-Gaussian (LG) beams. The dependence of…
