Laurent Arnoldi is an inventor associated with Rouen, France. His work includes a patent for a tomographic atom probe designed to analyze materials at the nanoscale.

Latest Patents

Arnoldi is credited with 1 patent: “Tomographic Atom Probe with Terahertz Pulse Generator.” The invention describes a tomographic atom probe that analyzes a nanotip sample inside an analysis chamber. The nanotip is mounted on an anti-vibration support, cooled to a temperature between 0 kelvin and ambient temperature, and held at an adjustable voltage between 1 and 15 kilovolts. A position-sensitive, time-of-flight ion detector records the evaporated atoms.

The device uses high-peak-intensity, single-cycle ultrashort terahertz pulses focused onto the nanotip. According to the patent description, these pulses cause atoms to evaporate through the field effect without thermal effects. A femtosecond pulsed laser generates the terahertz pulses from high-power ultrashort optical pulses.

Career Highlights

Arnoldi’s listed professional affiliations include Université de Rouen Normandie and Institut National des Sciences Appliquées de Rouen. His patent reflects work at the intersection of materials analysis, ultrafast laser technology, and atom-probe instrumentation.

Collaborations

His listed coworkers include Angela Vella and Jonathan Houard.

Conclusion

Laurent Arnoldi’s patent presents a terahertz-pulse approach to atom evaporation in tomographic analysis, connecting his work and Rouen affiliations with innovation in nanoscale materials characterization.
