  • Device for shaping a laser beam for an atomic sensor having retroreflector prism, linear polarizer, and form birefringence plate
    Patent number: 11002977
    Abstract: Device for shaping a laser beam for an atomic sensor, comprising a retroreflector prism with an entrance area, an exit area and two reflection surfaces forming a right angle therebetween. The device for shaping includes a linear polarizer disposed upstream from the entrance area of the retroreflector prism for linearly polarizing a laser beam entering into the retroreflector prism by the entrance area, and a form birefringence plate disposed downstream from the exit area of the retroreflector prism to circularly polarize a laser beam exiting from the retroreflector prism by the exit area.
    Type: Grant

  • Gas cell for an atomic sensor and method for filling a gas cell
    Patent number: 10775747
    Abstract: The invention relates to a gas cell for an atomic sensor, comprising an optical cavity provided with at least one optical window (9) and fillable with a gas. The cell also comprises a sealing cup comprising a cavity mouth, a channel mouth, and a sealing access, as well as a membrane which hermetically closes the sealing access of the sealing cup. The membrane can be plastically deformed by heating so as to hermetically close the cavity mouth and/or the channel mouth, in such a way as to hermetically separate the optical cavity from the gas inflow channel.
