If you mean "amplitude" in the quantum mechanical sense of the word, no. If
you mean "amplitude" in the sense of "strength", then no, all photons are
100% identical and fungible, so they all have the same energy content,
except for the "wavelength" which is controlled by how you're moving
relative to the source etc. But each photon of a given frequency has the
same energy as any other photon of a given frequency. A brighter light is
just more photons.
