Non-linear structured light in a self-imaging laser cavity based on III-V semiconductor nanotechnology
Résumé
We present a classification of the transverse light states observed in a 3D degenerated optical system using a specially design VECSEL based on III-V semiconductor nanotechnology with weak light confinement in matter. A broad transverse area system with low but tunable diffraction combine with saturable absorption is used for light confinement. These light states include CW paraxial spherical coherent beams linearly polarized, conical waves and spatially degenerate coherent light. A first result of a non-linear structuration is also shown.
