  • Device for generating a polychromatic photon beam having substantially constant energy
    Patent number: 11258227
    Abstract: Some embodiments relate to a generation device that includes: a pulsed laser source generating primary photons having at least one wavelength within pulses having time dissymmetry, a forming device(s) controlling the primary photons so as to generate a selective-polarization, focused input beam, and an optical fiber wherein the primary photons induce secondary photons having different wavelengths resulting from a raman conversion cascade and forming a wide-spectrum output beam having substantially constant energy.

  • Device for generating a polychromatic and spatially self-adapted beam of photons
    Patent number: 10718991
    Abstract: Some embodiments are directed to a generating device, including a pulse laser source providing primary photons having at least one wavelength, shaping device(s) acting on the primary photons to provide an input beam, a nonlinear crystal, and controller(s) generating, in the nonlinear crystal, at least one electric field that is synchronous with the input beam and suitable for inducing a phase mismatching in the nonlinear crystal through an electro-optical effect, in order to convert the primary photons of the input beam into secondary photons having wavelengths belonging to a supercontinuum.

  • Device for generating a beam of photons with wavelengths defining a substantially continuous supercontinuum
    Patent number: 10608403
    Abstract: A generating device includes at least one pulsed laser source that delivers primary photons having at least one wavelength in a single spatial mode and in pulses having a high pump energy, forming means that act on the primary photons to deliver an input beam, and at least one optical fiber having at least ten modes between which the pump energy is initially distributed, and able to relocate the latter via a non-linear effect into a fundamental mode, before generating secondary photons of various wavelengths by wavelength conversions from the wavelength of the primary photons in the fundamental spatial mode.
