Numerical investigation on the generation of high-order Laguerre-Gaussian beams in end-pumped solid-state lasers by introducing loss control.

This paper reports a robust and systematic approach to generate high-order scalar Laguerre-Gaussian (LGp,l) beams in end-pumped solid-state lasers by introducing loss control. Based on the spatial distributions of Laguerre-Gaussian modes and the theory of transverse mode selection, the "loss control" is implemented by an amplitude mask in the resonator… (More)
