Ok, Thanks. But we have a great number of photons that seem to affect the system significantly. How about that? Am I wrong about that?

Did you calculate the values I suggested?Ok, Thanks. But we have a great number of photons that seem to affect the system significantly. How about that? Am I wrong about that?

In a very simple model, we can take the electric field of an atom proportional to [itex]Did you calculate the values I suggested?

q/r^2

[/itex] in which q is the charge of nucleus and r is distance from its center. An electromagnetic wave is [itex]

E=E_0 exp(-i\omega t)

[/itex].I think we can consider [itex]

E_0

[/itex] as large as possible; can't we? Could you please guide me If I am wrong?

The energy density of an electric field in vacuum is ##\frac{\epsilon}{2} E^2##. Take a typical, weak laser with 1mW/mm^2, calculate the energy density, and calculate the average electric field based on that. The value is somewhere at a few V/cm.
