Generation of High-order Laguerre-Gaussian modes in Coated and Uncoated Graded-Index and Step-Index Multimode Fibers

Wasyhun Asefa Gemechu, Umberto Minoni, Michela Borghetti +4

We report an efficient experimental method for generating high-order Laguerre-Gauss (HOLG) modes by simply coupling a Gaussian beam into the cladding of a multimode fiber (MMF). In…

Concatenation of Kerr solitary waves in Ceramic YAG: application to coherent Raman imaging

Nicholas Bagley, Sahar Wehbi, Tigran Mansuryan +12

A coherent concatenation of multiple Townes solitons may lead to a stable infrared and visible broadband filament in ceramic YAG polycrystal. This self-trapped soliton train is lev…
