Laser light and how it works
Technically, the word laser is an acronym that stands for "light amplification by stimulated emission of radiation," or in simpler terms: light intensification by accelerated ejection of radiation.
Although the term has become so commonly used that it is no longer capitalized. The radiation is the light that is emitted from the laser; this light can be visible or invisible to the human eye. Technically, only some lasers use light amplification, but the name laser is still used for a device that produces monochromatic (all one color or wavelength), coherent (the light waves are similar enough to move in one direction) radiation. A laser light is made up of mechanical waves. |
LASER light is very different from normal light, because it has the following properties:

To make these properties occur it takes something called stimulated emission. This does not happen in the ordinary torch- in a torch all of the atoms release their photons randomly. in stimulated emission the photon projection is organized.
The photon that any atoms releases has a certain wavelength that is dependent on the energy difference between the exited state and the ground state. The ground state is when the atom is not exited, and the exited state is when the atom is energized. if a photon (that has a certain energy and stage) should encounter another atom that has an electron in the same excited state, stimulated emission can occur.
