The efficiency and focal length of each microlens are modified through the addressing voltage. This allows for a precise control on the energy coupled to the filaments thus obtaining a homogenized supercontinuum pattern from an inhomogeneous irradiance input distribution. Slight changes in the focal length of the microlenses allow for independent tailoring of the supercontinuum spectra. eng http://creativecommons.org/licenses/by-nc-nd/4.0/ info:eu-repo/semantics/openAccess Attribution-NonCommercial-NoDerivatives 4.0 Internacional Lenses Ultrafast optics Arrays Microoptics Laser beams Silicon compounds Laser theory Controlled Multibeam Supercontinuum Generation With a Spatial Light Modulator info:eu-repo/semantics/article
