The dynamic dipole polarizabilities for the 3s state of the Li atom are computed using Hylleraas and semiempirical approaches. This enables the calculation of the 7Li(2s→3s) Stark shift at photon wavelengths of 610.5 nm and 735.1 nm. They are calculated to be 834.7(5) and -686.7(25) a03, respectively. The first two tune-out frequencies for the 7Li(2s) ground state are determined to be 670.971626(1) nm and 324.192(2) nm, respectively.
