Finite Differences Beam Propagation Method in 3-D

3-D Simulation of a gaussian pulse propagated in free space

This set of simulations make use of the Alternating Direction Implicit method for solving the parabolic wave equation that arises in FD BPM.
The zip file includes the following programs:

FDBPM3D_free_space.m - Animation and video of the 3D propagation.
FDBPM3D_free_space_slice.m - It shows slices of the propagated pulse.
FDBPM3D_free_space_volume.m - It displays the laser beam as it would look in free space after a 1500 um propagation.
