I do not understand laser pointers in astronomy.

Well, professional astronomers use yellow sodium lasers to help their equipment made adjustments to compensate for any atmospheric disturbances. This results in a clearer image. Amateur astronomers use their little green lasers to point out celestial objects, just like people use the red lasers during the day. |

That explains professionals but I still don't understand how amateurs use them.

Does a certain layer of the atmosphere stop the laser beam or something?

No, the atmosphere doesn't stop laser beams, the beams just go so far, though I doubt we can see the end point that well. These go for about five miles. |

It's a bit spendy, though. I'd look about and see if there's a good quality laser at a lower price.
