The electronic cigarette is not new. People who buy electronic cigarette knows that this product has been in the market for years now. Despite some sectors apparently trying to shoot the product down from the shelves, the popularity of elect Active shredder safety technology for the small office. Shreds 15sheets per pass into 5/32" x 1-1/2" cross-cut particles (Security Level3). Patented SafeSense® Technology stops shredding when hands touch thepaper opening. Designated shredde

Atom:We have nearly 100 different atom types made available to us out of which several hundred combinations are formed to create applications of various types. There are several technologies which have taken birth from the basic element, atom. All the theories and technologies are rotating around atom which has the generic movement or vibrations or rotation. When a certain energy level is applied to the atom at ground state it gets excited and would leave ground state and enters into the next orbit level. In general, the energy applied and the shift in level would be proportional to each other.The energy converted to Light:What happens when the atom gets excited and moves to next orbit level, it will not stay there for long and would start falling back down to the same old ground state but with a mechanism of converting all of the energy it has acquired into light particles called as photons. The color of these photons would be directly dependent on the amount and type of energy applied on the atom in order to create photons. When you take the live example of TV, it is the common and regular phosphor atoms onto which the energy is applied, the end result of which is photons with different colors.What is laser?We hardly know about the wonders that happen with the laser light. With this light it is possible to break down the huge and strong crystals very easily and in very less time. To say, it is the laser light that does all the wonders. This laser light coming from the laser application is possible only when the photons that are released out of atoms are controlled through the light amplification of stimulated emission of radiation. This process is mandatory for almost all the applications that are based on laser technology like the powerful industrial applications of which few are laser engraving, cutting, cladding, drilling, bonding, welding and few other powerful applications.Details about the process:In general there are several laser types available in the market for which one could list down specific and unique features that are associated with all of them. All of these features are obtained through the process of pumping the lasing medium either with light flashes or with electrical discharges. Only with this pumping mechanism the lasing medium would attain the capability to create the large collections of atoms which are qualified as highly excited. When mentioned as highly excited, the atoms would contain highly energetic electrons. These highly energetic electrons would let laser applications perform well. While the common understanding is that no technology would function without the atom moving around, the more specific detail is that the laser technology would function well only when the atom is applied with sufficient energy and pushed to two levels upper than the present orbit level. This would increase the population inversion which is understood as the ratio between the excited atoms and the ground state atoms. While all this sounds good, for the laser to work effectively it is required that two identical photons having same wavelength are to be generated from two identical atoms on which same level of energy is applied. For this to happen the atoms are to be maintained in the same initial state before the energy is applied on them.Characteristics of laser light:Laser light is the light that comes from the photons emitted out of atoms that are excited from the ground to the next orbit level. In general this light from photon would have different characteristics from that of normal light which is why we are listing them out now.Monochromatic: This laser light would have one single wavelength which is made possible by controlling the energy level that is released during the electron drop down process.Coherent: Coherent light is characterized as being organized. This is possible when the photons  having wave fronts are launched in unison in turn resulting in cohesion.Directional: When you look at the normal flashlight you would see that the light is released in multiple directions which would end up in weakening and diffusing the light. This does not happen with laser light as it would be strong and tight in addition to having concentrated in a single direction which is why it can be called as directional light.Stimulated emission happens only when stimulation of light photons happens in order to emit laser light in an organized manner. This special feature of laser light is not available in flashlight which is where the laser technology takes pride of acquiring market with the endless solutions made out of it. In general the wavelength of the photon is defined as the difference between the lower orbit and the higher orbit levels between which the atom would shift its state when excited.The wavelength of one photon generated from one atom should be matching with the wavelength of the second photon coming from second atom which is when the real stimulation emission occurs after which the first photon group would be able to propagate the energy levels and the energy state shifts for the second chain of photons. The vibrations along with the frequency of the second chain of photons would be ensured to match with the first set of photons. The direction is also ensured to be one and the same between these propagations.For the photons to travel to and fro that would in turn result in the next chain of propagations, one should use half silver mirrors at the edges of the lasing medium. This laser mirror will help propagate the next chain of photons while allowing the initial set of photons to go out through the silver part of the mirror thus resulting in laser light which will address lot many use cases people are looking for out of laser applications.
