When a photon kicks a excited electron, why do the two released photons have the same polarization?
I was playing with some lasers and am trying to understand the principles at play. I just read about what polarization is in light waves, and I wonder: considering the excited electron is present at the edge of a particle, why does the released photon share direction and phase?
Honestly, I would have thought the released electron would be released in an angle or something. similar to what happens when two billard balls collide.
Can you elaborate a little bit about why this happens, please?
