Note:  Lasers are lasers  of electromagnetic radiation. Laser beams can be made from visible light, X-rays, ultraviolet rays or infrared light. Laser is a kind of excited and energetic light that is not seen in normal conditions in nature, butit can be createdwith special technology and equipment.

 Lasers differ from ordinary light in that these features  give them special capabilities and applications. Laser light is brighter and more intense than light in nature  . Laser light can crack the hardest metals and easily pass through hard objects such as diamonds and  create holes in them. Low power and ultra-thin beams Other types of lasers can be used to perform  very delicate tasks such as surgery on the human eye. Laser light can be controlled with great precision  and used as a continuous beam called a continuous laser or fast blasts called a pulsed laser  . Unlike ordinary light, laser light has a perfectly coordinated energy, which creates a lot of power  to do different things. The word laser is the first letter of the words that describe it  Its properties have been created, which means that light is amplified by the induced emission of radiation  . The difference between laser beam and ordinary light is in the important properties  that exist in this beam. These characteristics are: coherence, monotony, directness of  high intensity. These properties are not seen in ordinary light and these properties are  used for various tasks.




Nano lasers
(Nano-laser) is a laser that at the nanoscale  ,  these tiny lasers can be quickly modified and, along with  small  footprints , make them ideal candidates for optical computing  on a chip  . Areas of intense light such a laser also strengthening effect in nonlinear optics  or scattering (Raman Raman) with the increased level  possible, and  thus pave the way for circuits nano-photonic integrated pave , generally Nano Laser Nano Laser  rise  Or  amplification is a  process in which the environment transfers part of its energy to the emitted electromagnetic radiation  ,  resulting in increased optical power. This is the basic principle of all lasers. Quantitatively,  increasing  measurement is the ability of a laser medium  to increase optical power.
