Abstract
A Ramsey spectrometer is provided with an optical path, an optical path length stabilization circuit configured to stabilize a length of the optical path, a modulator optically connected to the optical path, the modulator being configured to generate resonant laser light of a first frequency f1 that causes a resonance of an atom, a molecule, or an ion as a spectroscopic target in pulses a plurality of times and generates non-resonant laser light of a second frequency f2 that does not cause the resonance, and a spectroscopic unit configured to spectroscope the spectroscopic target. The spectroscopic unit detects a state change of the spectroscopic target corresponding to the first frequency f1, the state change being caused by irradiating the resonant laser light to the spectroscopic target.
