Two standing laser waves of main and sideband frequencies of an optical lattice induce a Raman transition; due to resonant Raman driving the critical value of the transition parameter depends on the modulation strength and the detuning from resonance and can be tuned to a given value. It is shown that there is an interval of the initial MI phase, in which a modulation switches the MI phase to the SF phase.10 pages, no figuresCondensed Mattertext
