is a technique by which the Electromagnetic Spectrum Energy Agency is applied to facilitate its biochemical activity. The energy must be measured and calibrated so as not to saturate the live medium or on the contrary it is insufficient. Laser means Light amplified by emission of radiation (LIGHT by amplification stimulated emission of radiation).
is the Queresigna all the radiation wavelengths that emits a substance. It extends from values of wavelengths of the order of tens of km. Up to 10-14 m.
- · for the oscillation frequency of the waves.
- · for the wavelength between two successive crests.
The region between 10 km and a few meters, corresponds to frequencies of the order of 10-4 to 107 Hz. They are used in broadcasting and requires the use of conventional components and circuits. The continuous region corresponding to wavelengths from 10-1 to 10-3 m is the region of the microwave.
From the wavelength of 10-4 m and up to 10-8 m, the methods of obtaining radiation differ from the foregoing. This interval is called optical spectrum , where the region is perceptible by the human eye called visible spectrum, between 3,300 and 7,700 amstrongs.
The light spectrum represents the most important field for man within the electromagnetic system.
is composed of the frequencies in which rainbow colors are presented and covers wavelengths between 760 to 380 nm (nanometer 10-9 m). The minor wavelengths correspond to the Rx and Gamma regions.
Electromagnetic Waves:
are a vibrational disturbance produced by the simultaneous variation of two fields, electric and magnetic that usually vibrate in two perpendicular planes. For example, radio and light waves.
Physical parameters of the laser:
Wavelength: E S The distance traveled by the wave in a period. It is represented with the symbol & ldquo; l & rdquo; And his unit is the subway. The greater number of cycles performed in a second, the lower the distance traveled or wavelength.
Power: is the speed with which a job is performed. Using electric power is the product of v. I. In this case, it is used to measure the speed with which the transformation of one energy occurs in another. It is represented as & ldquo; p & rdquo; And it is measured in Watts. It is also defined as the ability to carry out a job.
How does the laser occur?
Certain electrons can jump into a state of metaestability, temporarily are at a higher level of energy because it has been raised to orbits more distant from the primitives by adequate stimulation.
By provoking the electron return to your normal situation, photonic stimulation is achieved. The external energy that requires this production can be thermal, luminous, electrical or chemical and its contribution is known as & ldquo; pumping system & rdquo;
