Latest Patents
One of Holleville's latest patents is a "Compact laser source with reduced spectral width." This invention relates to a laser source with an external cavity that generates a useful laser beam. It includes at least one laser diode mounted in an extended optical cavity defined between two reflecting surfaces. The design incorporates a mode selection filter to select a resonance mode from a range of resonance modes of the laser beam. The extended cavity features an optical device that includes a polariser, which is 100% permissive to a rectilinear polarisation of the beam generated by the laser diode. This invention has applications in cooling atoms, interferometry experiments, inertial sensors, and atomic clocks.
Another significant patent is the "Method for modulating an atomic clock signal with coherent population trapping and corresponding atomic clock." This method involves pulse-modulating laser beams to illuminate an interactive medium. It includes a detection process of the current pulse and preceding pulses, which are then superimposed to generate a compensated atomic clock signal with minimized spectral width. This invention is applicable to atomic clocks that utilize pulsed interrogation with thermal or laser-cooled atoms.
