When the laser is emitted from one direction, the divergence of the beam is very small, just like countless swords, the tips of which all point in one direction, so they can gather and burn objects instantly.

Aurora is just that electrons in the stream of electric particles emitted by the sun collide with atoms in the upper atmosphere of the two poles of the earth, because the electrons in it have very high charges, and the atoms absorb part of the energy of the electrons and release this energy to produce extremely intense light.

However, unlike laser, although the amount of aurora light is high, like ordinary light, the whole beam and photons propagate in disorder.
