Area of Science:

  • Atomic Physics
  • Quantum Optics
  • Magnetometry

Background:

  • Traditional absorption and polarization rotation methods have limitations in coherent state detection.
  • Parametric frequency conversion is a key process in nonlinear optics.
  • Atomic vapor cells are sensitive probes of magnetic fields.

Purpose of the Study:

  • To demonstrate stimulated microwave optical sideband generation for coherent state detection.
  • To develop a novel intrinsic magnetic gradiometer using this technique.
  • To assess the sensitivity and practicality of the developed gradiometer.

Main Methods:

  • Utilized stimulated microwave optical sideband generation via parametric frequency conversion.
  • Employed a density matrix formalism to model sideband generation.
  • Measured the beat note frequency between sidebands from two spatially separated ^{87}Rb vapor cells.

Main Results:

  • Achieved efficient sideband generation using ^{87}Rb atoms in coherent superposition states.
  • Demonstrated a magnetic gradiometer with sensitivity of 25 fT/cm/sqrt[Hz] and 4.4 cm baseline.
  • Operated the device effectively in a noisy, unshielded laboratory environment.

Conclusions:

  • Stimulated microwave optical sideband generation is a powerful tool for coherent state detection.
  • The novel magnetic gradiometer eliminates the need for intermediate magnetic field measurements.
  • The technique is readily implementable in practical, compact devices.
