The infrared  green laser pointer  also has some advantages. White spots on his face long does affect the appearance, so many people are looking for beauty freckle way, usually can only play a temporary role in the cover, you want to spot the real from his face away, or need some scientific methods of. Rejuvenation IPL freckle freckle is a good way. The following plastic surgery by the Beijing Lido expert to tell you about. Rejuvenation IPL freckle effect is very good, IPL skin rejuvenation is a non-invasive skin plastic medical technology, it has a comprehensive improvement of the effectiveness of skin from the base to solve skin problems, diminished fine lines, eliminate the stain, shrink pores, whitening skin. Rejuvenation IPL freckle first step: get rid of redness, skin light up. Point-like light sheet + light phototherapy of skin surface mesh sheet enclosed small bloodshot eyes, the deeper part of the laser dot thick closed vessel, together eliminate the redness, while improving the skin dull, heavy-hwan beautiful skin. The infrared  green laser pointer  has taken up some market shares.
Rejuvenation IPL freckle second step: solve the rough skin of water up. Phototherapy light stimulus + light cycle after mild stimulation of collagen, laser point-like cycle, high-intensity stimulation of deep blood vessels, promote blood circulation, to produce more collagen, to solve the skin rough, loose, thus making the skin smooth and delicate, crystal clear water tender. Rejuvenation IPL freckle third step: eliminate the stain, white skin up. Burst of light phototherapy light ablation of superficial skin and soft spots after ablation, Q laser will instantly burst into a small stubborn pigment pigment molecules, metabolism, excretion, completely eliminate freckles, sun spots and other spots, restores the skin smooth and fresh. IPL rejuvenation has numerous freckle spots a woman effectively solve problems, freckle while rejuvenation, if you have a spot of trouble, try this method, be sure to give you a different effect. Rejuvenation IPL freckle you want to know the price or other questions, please line with the hospital specialist. In fact, in addition to laser speckle, the majority of patients with traditional Chinese medicine freckle is now widely used means of a freckle, Vea beauty spot capsule beautiful community is the quality of supervision by the State Food and Drug approved by the Board of pure herbal products, is the speckle industry Jiao Johnson were. The customer can get more promotion if buying infrared  green laser pointer .
Starting from the regulation of the endocrine, is to remove all stain of the professional products market for many years more women to solve the trouble spots, but also for establishing a good reputation and image, get more people to trust and esteem. Theoretical studies have shown that any work material, under appropriate excitation conditions, in particular the level of the particle system to achieve population inversion between energy levels. If microscopic particles such as atoms or molecules with high energy and low energy level E2 E1, E2 and E1 energy level populations on the number density of N2 and N1, in the two-level transition between the existence of spontaneous emission, stimulated emission and stimulated transitions absorption transition, three processes. Transitions generated by stimulated emission of light by stimulated emission, and the incident light has the same frequency, phase, propagation direction and polarization direction. Therefore, a large number of particles in the same excitation of coherent radiation field produced by the stimulated emission light is coherent. Stimulated emission transition probability and stimulated absorption transition probabilities are proportional to the incident monochromatic radiation field energy density. When the two-level statistical weights are equal, the probability of the two processes are equal. In the case of thermal equilibrium N2 <N1, so spontaneous transitions dominate the absorption of light through the material is usually due to shock absorption and attenuation. Excitation energy can damage the outside thermal equilibrium leaving the N2> N1, this state is called population inversion. More discount will be provided for the infrared 200mw laser pointer.
In this case, the stimulated emission transition dominant. Light through a period of length l in the inversion state of the laser working substance (active substance), the light intensity increases eGl times. G is proportional to the (N2-N1) of the coefficient, called the gain factor, and its size is also working with the nature of the material and the laser light frequency. Period of active material is a laser amplifier. If, for some active substances on the two mirrors parallel to each other (at least one of which is part of the transmission's) constitute the optical resonator (Figure 1), at high energy particles will produce a variety of directions of the spontaneous emission. Among them, the non-axial propagation of light waves outside the cavity escapes soon: axial propagation of light waves able to spread in the cavity round-trip, when it spread in the laser material, the light intensity is growing. If the resonant cavity G0l small-signal gain is greater than one-way one-way loss δ (G0l is the small signal gain coefficient), can generate self-excited oscillation. The freeing shipping can be supplied for the large quantity order of green laser pointer.
State of motion of atoms can be divided into different levels, from high energy level when the atomic transition to the low level, it will release the corresponding photon energy (the so-called spontaneous emission). Similarly, when a photon incident on a level system, and work to absorb it, will lead from the low-level atomic transition to the high energy level (so-called stimulated absorption); then, part of the transition to high-level atomic transition to the low level will and release a photon (the so-called stimulated emission). These movements are not isolated, but often simultaneously. When we create a condition, such as the use of appropriate media, cavity, enough external electric field is amplified by stimulated emission of radiation to be more than the stimulated absorption, so overall, there will be photon emission, resulting in the laser. The infrared  green laser pointer  acts well in performance.
