Origin of Lasing Modes Changing from Low-Order Hermite-Gaussian modes to High-Order geometric modes in Off-Axis Pumped Degenerate Cavities

Not Accessible

Your library or personal account may give you access


The wave-packet representation for geometric rays are developed to unify the eigenmodes and geometric modes in the degenerate cavities. The comparisons between theoretical and experimental results provide deeper understanding of the ray-wave correspondence.
