Latest Patents

One of Tonello's latest patents is a device for generating a polychromatic photon beam having substantially constant energy. This invention includes a pulsed laser source that generates primary photons with at least one wavelength within pulses that exhibit time dissymmetry. The device also features a forming mechanism that controls the primary photons to create a selective-polarization, focused input beam. Additionally, an optical fiber is utilized, where the primary photons induce secondary photons of different wavelengths through a Raman conversion cascade, resulting in a wide-spectrum output beam with substantially constant energy.

Another notable patent is a device for generating a polychromatic and spatially self-adapted beam of photons. This invention comprises a pulse laser source that provides primary photons with at least one wavelength. It includes shaping devices that act on the primary photons to create an input beam, along with a nonlinear crystal. Controllers generate an electric field in the nonlinear crystal that is synchronous with the input beam, facilitating a phase mismatch through an electro-optical effect. This process converts the primary photons into secondary photons that belong to a supercontinuum.
