The part about stimulated emission is wrong as it implies that the emitted radiation is released in random direction.
One atom spontaneously emits a photon in a random direction, true.. this photon then collide with another _excited_ atom that immediately emits a photon of the same phase, energy (color) and _direction_ as the incoming photon. This is stimulated emission.
As the photons bounce between the mirrors the majority of the photons get the same direction and phase.
