Gas cell for atomic sensor and gas cell filling method

摘要

The invention relates to a gas cell (2) for an atomic sensor (1) comprising an optical cavity (11) provided with at least one optical window (9) and capable of being filled with a gas. The cell also comprises a sealing cup (13) comprising a cavity port (14), a channel port (15) and a sealing channel (16) in addition to a membrane (18) that seals the sealing channel of the sealing cup. The membrane (18) can be plastically deformed by heating to seal the cavity port and / or channel port in such a way that the optical cavity (11) is hermetically separated from the gas inlet channel (17). It is.
