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 photon beam having substantially constant energy

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 polychromatic and spatially self-adapted beam of photons

The invention relates to a method for triggering a pulsed light source, wherein it comprises at least one iteration of the following steps: receiving a control signal; determining what is called a separation time between the reception of said control signal and at least one preceding control signal; adjusting at least one control parameter of said pulsed light source depending at least on said separation; generating at least one electrical signal for triggering the pulsed light source depending on said at least one control parameter adjusted during the preceding step; and triggering the pulsed light source depending on said at least one triggering electrical signal.
