THz-wave sensing with two-photon spectroscopy of cold trapped HD+
: The comparison between precision spectroscopy measurements with cold trapped HD + ions and accurate predictions of the molecular ion theory is exploited to characterize a THz electric field. A THz-wave off-resonantly coupled to the rotational transition at 1.3 THz may be detected by measuring the lightshift induced on a Zeeman component of the two-photon rovibrational transition at 55.9 THz. A set of six lightshift measurements for two different orientations of the magnetic field in the ion trap can be converted into the amplitudes and the phases of the THz electric field components in a Cartesian laboratory reference frame.
