What Does To be Mean
The term laser comes from the English laser , which is an acronym that arose from the expression Light Amplification by Stimulated Emission of Radiation . This expression can be translated into Spanish as Amplification of Light by Induced Emission of Radiation .
A laser, therefore, is a device that makes it possible to amplify a coherent and monochromatic beam of light through an induced emission (or stimulated emission). The concept is also used to name the beam emitted by this type of device.
A coherent radiation is one that keeps its phase difference unchanged beyond time . The light waves, in this way, maintain a phase relationship that is constant. Monochromatic, on the other hand, refers to a single color.
A laser has an optical cavity that allows light to circulate . In this cavity there is an active medium that is responsible for the amplification of light, for which any energy is required . This energy, in turn, is usually provided by an electric current or another beam of light.
Lasers have multiple applications. With the laser it is possible to record a large amount of information in microscopic spaces, just as it is done on a Blu-ray , a DVD or a CD .
A laser can also be used to mark glass, plastics and metals or sublimate various kinds of materials. This is due to the intensity it can achieve.
In the medical field , lasers allow surgical interventions and contribute to healing. The telecommunications , the civil engineering and archeology are other areas of application.
In the same way, we cannot ignore that there is also what is known as a lightsaber or lightsaber. It is a fictional weapon that is known throughout the world because it was created for the "Star Wars" film saga, also called "Star Wars".
It is a sword similar to the traditional one, but with the exception that its blade is a beam of light or energy. In addition, it should be noted that when it is fought with it, it gives off a very peculiar sound, specifically the same that arises when there is an interference.
It is also interesting to know that there are several different types of lightsabers. Specifically, we can highlight the following:
-The dark saber, which is black and whose blade resembles that of a katana.
-The shoto, which consumes less energy than a normal lightsaber and has a shorter blade.
-The one-bladed saber, which can go from blocking shots to cutting all kinds of materials. It is the most traditional sword in the 'Star Wars' movies.
-The double-bladed saber, which can be of various colors and differs from the previous one because it is much more precise and accurate. Among the characters in the saga who use it are Jastus Farr or Darth Maul.
Likewise, it also has other varieties such as the tonfas of light, also known as shoto de guard, or the whip of light.
