pumping band-
Abstract : we have studied theoretically a beat effect in a four - level system due to fifth - order optical polarization, and considered the cases that the pump beams have either narrowband or broadband linewidth. we have found that the accuracy for the energy - level splitting measurement is determined by the homogeneous linewidths of the optical transitions. that is to say, this technique can achieve doppler - free precision in the measurement of the energy level splitting between two excited states which are dipolar forbidden from the ground state
