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.
