    This should be rather labeled as Lecture 17 and not 18.

    Why this stimulated photon is not get absorbed by electron?

    But why is it called "Optical"??

    Why is he not choosing the maximum of the valence band and the minimum of the conduction band? He rather chose random points in VB and CB.

      His random point is mostly from the valley of CB, that whole valley region are stable states for electrons of CB. Electrons belongs to such region have the highest probability to participate in emission.
