We report our observation of a direct transformation of a Gaussian-like laser beam, initially injected into the cladding of a graded-index multimode fiber (MMF), into a high-order Laguerre–Gauss (LG) mode within the fiber core.

Abstract
We report our observation of a direct transformation of a Gaussian-like laser beam, initially injected into the cladding of a graded-index multimode fiber (MMF), into a high-order Laguerre–Gauss (LG) mode within the fiber core.File in questo prodotto:
