Abstract: On the basis of the analysis of various fast Hankel transformation(FHT) algorithms, the quasi-discrete Hankel transformation(QDHT) is chosen to study the beam propagation through multi-pass laser amplifier system containing a spatial filter. Numerical examples show that FHT is a useful fast algorithm to simulate the beam propagation through a large high power laser amplifier system with cylindrical symmetry.
