Results of numerical simulation show that the properties of “dark line” in the fluorescence spectrum and coherent microwave emission appear as the difference of frequency of two coherent laser beam excites the 87Rb gas cell.

According to a simple calculation model, both the power spectrum formula and the coherent harmonic radiation formula are derived.
