Dann können 2 Photonen quasi miteinander wechselwirken, oder?
Gibt es denn da experimente dazu?

Ist wohl eine technische Herausforderung, siehe z.B.

Experiments on the observation of the processes involving photon-photon collisions are extremely difficult to perform, because they are crossed-beam experiments which require the highest intensities and the most sensitive detection equipment. For this reason at the present time the photon-photon cross sections are still of little interest to the experimental physicist. The scattering of photons by a Coulomb field (Delbrück scattering) is the only observable case at the present time.

Delbrück-Streuung ist die bereits erwähnte Streuung eines Photons am Kernfeld.
