High Sensitivity Optically Pumped Quantum Magnetometer

Figure 4

Power spectral density of the photodiode output normalized to the resonance frequency. The spectrum was measured in a 1 Hz bandwidth. The signal was recorded with optical power of 20 μW and cell temperature of 50°C. The intrinsic and actual signal-to-noise ratios are highlighted.
