| Research Abstract |
We developed a spin noise spectroscopy system, which measures the fluctuation spectra of Faraday (Kerr) rotation by a spectrum analyzer, and the nuclear magnetic resonance of Cs atoms was observed by using a tunable diode laser with a narrow line width at 852nm. The sensitivity was improved by replacing the spectrum analyzer with a real-time FFT system, realized by a combination of FPGA and 14bit-800MHz digitizer. We challenged single spin detection in an InAs quantum dot in a microscopic spot at low temperature, but the signal was below the observation limit.
