Editing Lasers and Photonics (section)

* '''Laser''' — An acronym for "Light Amplification by Stimulated Emission of Radiation."
* '''Photonics''' — The science and technology of "Generating," "Detecting," and "Manipulating" light (Photons).
* '''Coherence''' — The property of laser light where all waves have the "Same Frequency" and "Phase" (they 'March together').
* '''Stimulated Emission''' — The "Spark" of a laser: when a photon hits an excited atom, it causes the atom to "Release a Twin Photon" that is identical in every way.
* '''Population Inversion''' — The "Condition" needed for a laser: having "More atoms in an excited state" than a "Ground state" (The 'Fuel' of the beam).
* '''Optical Cavity''' — The "Hall of Mirrors" in a laser that "Bounces" photons back and forth to "Amplify" them.
* '''Monochromatic''' — Light of a "Single Color" (Wavelength).
* '''Semiconductor Laser''' (Laser Diode) — The tiny lasers found in "Barcode Scanners" and "CD Players," made of the same material as "Computer Chips."
* '''Fiber Optics''' — The use of "Glass Threads" to carry "Light pulses" over "Thousands of miles" with "Zero loss" of data.
* '''Li-Fi''' — The future of "Wi-Fi" using "LED Light bulbs" to send "Internet data" at 100x the speed of current radio signals.
