RESUMO
We first report a single-light-source orthogonally pumped triaxial atomic magnetometer with a double-cell structure. By using a beam splitter to equally allocate the pump beam, the proposed triaxial atomic magnetometer is responsive to magnetic fields in all three directions, and without sacrificing system sensitivity. The experimental results indicate that, the magnetometer achieves a sensitivity of 22â fT/Hz1/2 in x-direction with a 3-dB bandwidth of 22â Hz, a sensitivity of 23â fT/Hz1/2 in y-direction with a 3-dB bandwidth of 23â Hz, and a sensitivity of 21â fT/Hz1/2 in z-direction with a 3-dB bandwidth of 25â Hz. This magnetometer is useful for the applications that require the measurements of the three components of the magnetic field.
