LASER often aesthetic medicine, has benefited from advances in technology, but a technique has rarely had an impact so large and so many possibilities such as lasers. Laser The acronym comes from English and means (Ligh Amplification by Stimul Emission of Radiations), which is translated into Castilian (extension of light by stimulated emission of radiation). WHAT IS LASER? In 1957 was first proposed the theory of lasers, two American scientists named ARTHUR SCWLOW and Charles Town. However, not until 1960 the first laser was built by another American scientist named THEODORE Maiman, based on a synthetic ruby rod and activated by a flash of light normal. Since then research has shown that many materials of the ruby laser beam light. The laser light is more intense than is known, even more than the sunlight. The laser emits a beam of light organized differently from a normal light bulb or the sun. In these differences are precisely the properties of the laser. The light travels in a continuous wave power. The highest points are called peaks and lower valleys are called. The light is measured in two ways Ø For wavelength (the distance between two peaks) Ø For the frequency (the number of oscillations per second) decomposes white light through a prism, in seven basic colors red, orange, yellow, blue, indigo and violet. They make up the white. Each color has a particular wavelength. The violet has the shortest wavelength and red the longest, the other colors have an intermediate length compared to violet and red. To provide a spectrum of electromagnetic waves that we wave the longer the AUDIBLE followed RADIO WAVES Ø 10 to Ø 8 INFRARED MICROWAVE Ø Ø Ø VISIBLE ULTRAVIOLET RAYS X Ø Ø Ø GAMMA RAYS COSMIC RAYS 10 to the -16 lightbulb emits light in different wave lengths. The vision of the eye or visible spectrum is 400 nm. and 750 nm. Like the normal light bulb, is scattered in all directions, so it loses lots of energy. In all the laser wave moving towards the same direction. We have a second point of differentiation in the laser. ADDRESS. Waves not only have the same laser wavelength and frequency, but they spread them all in phase, ie, andalusia step. HOW DOES THE LASER? Describe a basic laser gas consists of a glass tube filled with gas, which is stimulated by an electric current through it. Two mirrors, a reflection into the tube and a total partial reflection. The current excites the atoms (or molecules of gas) going to cast photons (light energy). Some of the photons collide with other atoms excited by the current, which in turn emit other photons. This is called stimulated emission of radiation. Amplification occurs because when a photon hits an excited atom, produces another photon identical to itself, both in energy and phase. The two photons can in turn collide with other excited atoms to produce photons and back again so that to produce new photons. WHAT KIND OF REACTION PRODUCES THE LASER? Adequate and sufficient irradiation of the skin (either chosen the type of laser and time depending on the energy necessary to produce the following effects Ø Increased cell regeneration (number of cells in mitosis) Ø Best reabsorption of interstitial fluid (the anti-edematous) Ø Increased collagen, activation of neosíntesis within fibroplasto. Ø Increase the number of functioning capillaries (better vascularization of the land). Ø Increased muscle (direct action on puntosn command). The laser reequilibrante and acts as a normalizer of the functional activity of the cell membrane. ENERGY EFFICIENCY Not all energy densities have the same effectiveness, those with higher value that we have greater efficiency as well as those obtained in less time. When a some energy density is obtained with a team from a higher power, energy efficiency of implementation is reduced, efficiency is increased exponentially. This concept may seem completely theoretical, clinically we have seen the truth of it. The treatment results in an equal dose made with a team of 3 miliwatios far from those obtained with a 30 miliwatios. The same is true when we make a specific treatment, various applications in small areas is getting better and faster results when radiates throughout the area affected by a manual or automatic scanning with the same energy density, and, moreover, is aggravated by the energy that was always much less precise in dealing with this timely and much less time employment. treatment point energy efficiency is always higher because the areas of application are very small. The greater or lesser efficiency of the entire application will determine the degree of reaction FOTOBIOLÓGICA tissue receiving such irradiation, the absorbed and transformed. The theory supports the greater efficacy of combined treatments of conduct so that applied sequentially, an enhanced activity of the other irradiation, thus reaching the conclusion that it would be a synergy of the other. With a device unless it is necessary to increase intensity treatment time for the tissues that receive the required dose of light energy. 80mW IR LASER DESKTOP
