I don't know how is this even A-level topic....You explained much better than my Photonics lecturer in uni, no overdose of math that only causes confusion, only the raw, abstract concept.
I think you should emphasize that for the stimulation emission to occur, the atom should be in the excited state. therefore when it is hit by a new photon, the atom will go to the ground state and 2 photons are generated (one from the hitting photon, the other from atom coming back to the ground state)

Thank you so much, the concept is very well explained!
Thanks a lot for the awesomeeee explanation!
at 3:13 I think you mean electrons instead of atoms I'm not sure though I'm just finding this a bit confusing
Brandon White thank you I appreciate the help
you are right he meant electrons, atoms don't move up and down energy levels
@@BZaks no the atoms absorb the photons which make electrons move up energy levels
@First Name Update: I went from a D student to actually get a B (almost A :( )and I seriously attribute all of my success to this channel
3:10 how come it doesn't go back down to ground state and release a photon?
how come spontaneous emission doesn't take place?
He stated that photons are absorbed by the level that has larger numbers of electrons
Sorry to tell you but this was actually quite confusing. It made me understand less
