Research areas

    • Nonlinear optics
    • Multi-photon absorption and Multi-photon fluorescence studies
    • White-light continuum Z-scan and Nonlinear spectrometer development

Dr. Leonardo De Boni studies linear and nonlinear optical properties of organic materials, such as perylenes, azocompounds and other organic dyes. Ultrafast pulses are employed to investigate resonant and nonresonant nonlinear absorption spectrum and molecular dynamics. White-light continnum Z-scan is applied to observe the complete nonlinear spectrum in one single measurement. A nonlinear spectrometer is used to observe transient absorption.
