Computation of tightly-focused laser beams in the FDTD method
We demonstrate how a tightly-focused coherent TEM(mn) laser beam can be computed in the finite-difference time-domain (FDTD) method. The electromagnetic field around the focus is decomposed into a plane-wave spectrum, and approximated by a finite number of plane waves injected into the FDTD grid usi...
