Cell for optically pumped magnetic sensor
A cell for a optically pumped magnetic sensor measures magnetic field by setting alkali metal atoms to a predetermined excitation state by a pump beam and detecting the excitation state by a probe beam. The cell is provided with a glass substrate which seals the alkali metal atoms and an enclosing gas and transmits the pump beam and the probe beam and a coating layer provided on an inner surface of the glass substrate. The coating layer is made of an inorganic material.
