Numerical study for selective excitation of Ince-Gaussian modes in end-pumped solid-state lasers

This study report a first systematic approach to the selective excitations of all Ince-Gaussian modes (IGMs) in end-pumped solid-state lasers. The proposed Ince-Gaussian mode excitation mechanism is based on the "mode-gain control" concept. This study classifies IGMs into three categories, explores and verifies approach to excite each IGM category using numerical simulation.
