Light Amplified by Stimulated Emission of Radiation - Touch and Go

Have you ever wondered word the word “laser tag” comes from?
It’s etymology?
Did you know it is actually two acronyms?

An acronym is a word that is formed from an abbreviation from initials (usually the first letter) of a series of words.


You might have known that "Laser" was an acronym. Laser is short for “light amplified by stimulated emission of radiation”.
Officially, according to Wikipedia a laser is a device that emits light through a process of optical amplification based on the stimulated emission of electromagnetic radiation.
A Laser emits coherent light and it is used in lots of equipment such as laser printers and barcode scanners.
Interestingly, the Laser Tag in a Box system from Battlefield Sports does not actually use any lasers. Instead the system uses digital infrared and digital radio.
Just like an oversided TV remote! In the shape of a phaser!


While "tag" the word is a noun that is the name for the in which one player chases the others in an effort to touch one of them, who then takes the role of pursuer. And it is also a verb to touch or hit as part a game of tag.
But it is also unknown as an acronym, i.e. short for "touch and go!"
So if you put Light amplified by stimulated emission of radiation plus Touch and Go together you get Laser Tag!
