Measurements within 10% accuracy of the dynamic dipole polarizabilities alpha(lambda) for five nonrefractory metal atoms (Mg, Ag, Al, Cu, and Au) at laser wavelengths of lambda=532 and 1064 nm are presented using electrical explosion of thin wires in vacuum and a novel laser probing integrated-phase technique. The technique is based on single-wavelength interferometry and does not require axial symmetry of the tested object. Theoretical prediction of alpha(lambda) for wavelengths lambda=355, 532, and 1064 nm, as well as the static dipole polarizabilities alpha(st), are also presented. An agreement within 20% was obtained between calculated data, recommended static polarizabilities alpha(st), and the measured dynamic polarizabilities alpha(532 nm) and alpha(1064 nm).
