The pure FFLO state, characterized by finite center-of-mass momenta q \\ne 0 of Cooper pairs occurs in the two-dimensional limit, when the magnetic field is parallel to the conductive plane. The vectors q are determined from the Fermi-surface structure and pairing anisotropy, and become finite below a temperature T^*.
