Laplacian gauge fixing was introduced [1] to find a unique representative of the gauge orbit, which on the lattice could be implemented by a ''finite'' algorithm. What was still lacking was a perturbative formulation of this gauge, which will be presented here. However, renormalizability is still to be demonstrated. For torodial and spherical geometries a detailed comparison with the Landau (or Coulomb) gauge will be made.
