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.
