Typically, the sale of laser pointers is restricted to either class 3A (<5 mW) or class 2 (<1 mW), depending on local regulations. For example, in the US, Canada and the UK, class 3A is the maximum permitted, unless a key actuated control or other safety features are provided. [ 31 ]
Also, any laser with class higher than IIIa (more than 5 milliwatts) requires a key-switch interlock and other safety features. [67] Shining a laser pointer of any class at an aircraft is illegal and punishable by a fine of up to $11,000. [68] All laser products offered in commerce in the US must be registered with the FDA, regardless of output ...
The word laser is an anacronym that originated as an acronym for light amplification by stimulated emission of radiation. [1][2] The first laser was built in 1960 by Theodore Maiman at Hughes Research Laboratories, based on theoretical work by Charles H. Townes and Arthur Leonard Schawlow.

Laser cutting. Laser cutting is a technology that uses a laser to vaporize materials, resulting in a cut edge. While typically used for industrial manufacturing applications, it is now used by schools, small businesses, architecture, and hobbyists. Laser cutting works by directing the output of a high-power laser most commonly through optics.
