Where to Buy Laser Guide Stars
Laser beams can be used to generate artificial stars, creating bright spots in the sky that can be used for astronomical instruments. These guide stars help detect atmospheric distortions, allowing adaptive optics to compensate for them and improve the quality of astronomical observations.
