Laser beams are [[phase coherent]] and self-[[parallel]] (they do not spread out), due to the way they are created, although many cheap laser pointers exhibit beam dissipation due to cheap manufacturing.

This is much more of a problem with Indian and Chinese-manufactured components, as American manufacturers are held to higher standards in workmanship and materials. <ref>http://www.thechinaexpat.com/what-everybody-ought-to-know-about-chinese-manufacturing/</ref>

The use of lasers is very important in [[science]] and [[medicine]]; they have also become ubiquitous in [[CD-ROM]] and [[DVD]] players and as pointers.
