Abstract
In connection with designing and engineering of the new generation for ultrastable optical frequency standards, some theoretical aspects of the Stark spectroscopy for cold alkaline-earth atoms in a 3D-optical l attice are considered. In this paper the main attention has been paid to the polarization and dispersion properties of these atoms, depending on power, frequency and polarization of the trapping laser sources. A "light shift cancellation regime" is analyzed, in which the second order dynamic polarizabilities of the upper and lower levels become equal to each other for the forbidden "clock" transitions 3Ρ0− 1S0 and 3Ρ1− 1S0. The laser wavelengths for this regime ("magic" wavelengths) have been determined. In the particular case of Sr atoms we have calculated the values for the 4th-order dynamic susceptibilities (hyperpolarizabilities), as well as the higher-order multipolarity contributions to the dynamic polarizabilities of the 3Ρ- and 1S-levels

for ultrastable optical frequency standards, some theoretical aspects
of the Stark spectroscopy for cold alkaline-earth atoms in a

which the second order dynamic polarizabilities of the upper and
