  • Device for cutting a structure including wire-like nanoscale objects, and related method
    Patent number: 9211610
    Abstract: A device for cutting a structure including nanotubes, including: a mechanism to polarize linearly laser pulses emitted in a direction of the structure, wherein a duration of the laser pulses is roughly between 1 femtosecond and 300 femtoseconds; and a mechanism to focus the linearly polarized laser pulses on the structure.
    Type: Grant
    Filed: December 14, 2011
    Date of Patent: December 15, 2015
    Assignee: Commissariat a l'energie atomique et aux energies alternatives
    Inventors: Pascal Boulanger, Olivier Sublemontier, Olivier Gobert
  • Stabilized femtosecond pulsed laser and stabilization method
    Patent number: 8953653
    Abstract: The present invention relates to a high-power femtosecond pulsed laser, the laser including: a source able to generate a train of input laser pulses having an envelope frequency and a carrier frequency; a chirped pulse amplification unit; and, a unit for controlling the phase drift between the envelope frequency and the carrier frequency of the output laser pulses. According to the invention, the unit for controlling the phase drift between the envelope frequency and the carrier frequency includes electro-optical phase-modulation unit that are placed on an optical path of the chirped pulse amplification unit in order to stabilize the phase drift between the envelope frequency and the carrier frequency of the output laser pulses as a function of time.
