In LASERS, when the initial stimulated photon gets emitted, it stimulates other photons to get emitted. Now my question is: Does the wave of this photon interfere with other waves and makes a bigger amplitude wave or we get two waves of same frequency and in same phase?
If we get two waves of same frequency and in same phase, what is the reason for having both waves in phase.isn't the first wave had just stimulated other atom to de excite? Why the new wave released should be in phase with wave stimulated its release(or produced it in general sense). Is there any principal behind this phenomenon or is it just a practical observation. Thanks.
