i was pming today Laser Pointer Forums - Discuss Lasers & Laser Pointers - View Profile: piferal
and we were talking about how its fun to learn about other uses for high powered lasers other than popping balloons etc.
share them here!
examples:
medical field..
astronomy..
construction...
CNC ..
what got us on this topic was this post:

The color of this laser is not chance, or whim, has a very specific use,
I will try to explain as best and simple as possible with my bad English.
The adaptive optics systems of the telescope require a nearby reference
bright star source, that has to be relatively bright in order to correct
atmospheric distortion of light and properly adjust the optics.
This is where this yellow laser enters in action.
Pointing this beam in the sky, this laser beam energizes the layer of sodium atoms that is present
in Earth's atmosphere at an altitude of ~90 kilometres, and this atoms glow, creating
a kind of artificial star, to properly adjust the adaptive optic to the specific zone,
this is because sometimes there are not enough bright stars present in all parts of the sky.
