Axially-functionally graded materials are/ types of traditional composite materials in which the mechanical and physical properties are gradually varied from one end to the other. They were used ...
Abstract: This letter proposes a new method for controlling the divergence angles of multimode orbital angular momentum (OAM) vortex beams. A geometric framework is established that allows for the ...
Abstract: We investigate beam shaping and field evolution in unstable optical resonators using a hybrid numerical scheme that combines the Split-Step Fourier Method (SSFM) with the Angular Spectrum ...
