The Impact of the Lasers Technology on Society

Introduction:

The name LASER is an acronym for Light Amplification by the stirred Emission of Radiation. In 1917, Albert Einstein first theorized about the dish out which makes lasers possible called Stimulated Emission. In this paper, we back end view the pertain of the lasers technology on society from four perspectives: the strength, the weakness, the opportunity and the holy terror of Lasers Applications. To sum up, we will focus on the future of Lasers on society, assessing the real value of the Lasers technology.

The strengths:

Lasers, broadly speaking, are devices that generate or amplify perch, just as transistors generate and amplify electronic signals at audio, radio or microwave frequencies. Since laser light brush aside be focused to a very olive-sized point of light, lasers are used in CD players, in surgery, in communication, in welding, in cutting, in spectroscopy and in printing industry.

Looking at the advantage of the laser, we can find that on that point are four peculiar(prenominal) of laser light. Comparing with the otherwise conventional technologies, one of the most frequently used characteristic of laser technology is that of coherent. That is, the emitted light waves are in class with one another and are so nearly parallel of latitude that they can travel for long distances without spreading.



Here light must be understand broadly, since lasers have covered radiation at wavelengths ranging from infrared range to ultraviolet and even soft roentgenogram range.

Take surgery as an example, when light is focused, the point of focus can become hot enough to burn the skin or human tissue, if the intensity of the light is great enough. This characteristic can be used to perform surgery that results in little damage than it a knife or scalpel was used.

Another example of this may be given. Focusing a very high push laser beam on a piece...
