Very often we hear stories about lasers The various aspects are always better in the film: the laser seems to be getting major roles for both business and leisure travelers. The film presents the world's point of view the future, hardly have nowhere that lasers do not have access to joint participation in. The laser beam is taken live via the investor perspective to create a movie is both a high-tech weapon to destroy all things or in the role of surgical remedies and in many other roles make lasers become outside interest of others.The principle of laser I have to learn from the Internet that was concluded by a laser beam of light that has properties different from regular light. There is a small beam intensity is higher than conventional lighting including light deviation is less than (low-divergence beam) is the frequency of light only one frequency.Laser (LASER) corresponds to the English word Light Amplification by Stimulated Emission is that of Radiation, which is interpreted as extending the main radiation of light-based nu-tun. Optical zoom is to increase the number of photon or light intensity increases, there is greater than ever. By normal atoms or molecules are always in low power class (E1), because it is the more stable state, but when the atoms or molecules are stimulated to absorb light or power sources excite the atoms or molecules, or make based in higher-energy (E2), but this power class E2 energy State is unstable, so it can probably only temporary, so it spit out power to make himself in condition stabilized again in power level E1. So I think the energy that an atom or molecule released so it is equal to the energy difference between the E2-E1 spit out light emitting or energy in this manner is based on this phenomenon that we call nature, shining a light happen myself (Spontaneous Emission)Discovery A laser is a device that allows the light energy from a laser beam. There is a wide range of properties depending on the design and implementation. Laser discovery occurred in 1954 by the sea. 27. ทาวน์ส (C.H. Townes) have been proposed as a principle or theory about laser removal, which works in the time he has been participating to get Nobel. Physics in the year 1964, the principle of the sea. 27. ทาวน์ส (C.H. Townes) causing the impetus to study laser technology matters and have the presence of far kwa series page by in May. 1951 1960 Theodore my man (Theodore Maiman) have done research, and research on lasers at the Research Institute, Hugh (Hughes Research Laboratories)
