The Phenomenon of Rabi Spectrum Broadening Caused by the Colored Noise
In this paper,the phenomenon of the two-level Rabi spectrum broadening caused by the colored noise is studied.For three kinds of colored noise with three different time-dependent characteristics,the Rabi spectrum under near-resonance conditions is nu-merically simulated by the fourth-order Runge-Kuta method.It is found that under near-resonance conditions,increasing the noise amplitude increases the Rabi spectrum broadening for a given measurement time.The closer the measurement time is to π/Ω,the smaller the noise amplitude is for the Rabi spectrum broadening of less than 10%.At the same time,the Rabi spectrum broadening is enhanced at low frequencies.The study in this paper has a certain effect on the suppression of the noise of the local oscillator of the optical lattice clock and the improvement of the measurement accuracy of the optical lattice clock.
