General expressions of Goos-Hanchen shift for both s and p polarizations from absorbing medium has been derived in this paper. Let the extinction coefficient be equal to zero, they will be simplified to the formulae[1] given by M. McGuirk and C. K. Carniglia, which are only fit for non-absorbing medium. The shift from absorbing medium occurs at any incident angle except zero angle. On Gallium surface, Goos-Hanchen shift may have several wavelengths.
