A novel approach to selective wavelengths emission in mode-locked Nd:YVO<sub>4</sub> lasers via photon emission angles Open
In this study, we successfully switched the wavelength of a mode-locked pulsed laser output from 1064 nm to 1086 nm by selecting the initial spontaneous emission photons for amplification inside the laser cavity. This was achieved by preci…

Observation of spatial nonlinear self-cleaning in a few-mode step-index fiber for special distributions of initial excited modes Open
In this paper, we experimentally demonstrate that a nonlinear Kerr effect in suitable coupling conditions can introduce a spatially self-cleaned output beam for a few-mode step-index fiber. The impact of the distribution of the initial exc…

Nonlinear spatial reshaping of pulsed beam in a step-index few-mode optical fiber Open
In this paper we demonstrate the spatial and spectral dynamics of pulse propagation in a step-index few-mode optical fiber, through an experimental and numerical analysis. The Kerr induced spatial self-cleaning is demonstrated by coupling …
