PURPOSE:To limit the function of control to the one only for the stabilization of a set of laser for excitation, by exciting an atom beam by excitation light from the laser for excitation and the excitation light obtained by shifting the above excitation light. CONSTITUTION:An optical frequency shifter 11 consists of an acoustic optical element using Brillouin diffusion, and is arranged between the laser 2 for excitation and a level selection area D, and frequencyshifts a part of the output light of the laser 2 for excitation from a frequency nu1 to a frequency nu2=nu1+nu0. In such a case, the optical frequency shifter 11 executes frequency shift by using the microwave of the frequency nu0 synthesized by a frequency multiplier 10. Consequently, it follows that two kinds of excitation light with frequencies nu1 and nu2 are supplied to the level selection area D, and excitation due to the excitation light with two wavelengths can be realized.
