| Oct 3, 2013 at 4:01 | comment | added | rajb245 | The point is that even a single photon traveling through an aperture (hole at the end of the laser cavity) is scattered (deflected) by it. The wave function exists over the entire aperture and diffracts through it. You can't decouple wave and particle views. | |
| Oct 2, 2013 at 22:38 | comment | added | BarsMonster | @rajb245 What if we have first photon, and then his "replica" is generated due to stimulated emission in gain medium. Will we have 2 photons flying in exactly same direction? | |
| Oct 2, 2013 at 22:19 | comment | added | rajb245 | Photons are wavelike, in that they are quanta of wave functions. The two descriptions are inexorably linked. | |
