I was reading about LASER production when I came by the concept of stimulated emission.
The book I was reading doesn't elaborate the topic much,so far I have understood what stimulated emission is but not how it happens.
When a photon strikes an excited atom the atom falls to it's ground state releasing another coherent photon.
To me, what should happen is that atom should gain energy and jump to a higher state(this is what normally happens).
Please elaborate this concept. Thank you.
