Is 100-400 nm wavelength electronic wave to ultraviolet ray, it is one of the invisible part of the spectrum, to reach the ground ultraviolet wavelength is larger than 290 nanometers, shorter than 290 nm ultraviolet ray is absorbed by the atmospheric ozone layer. In a production environment where objects of...[Detailed]

Due to the nature of the laser, can make the energy concentration in space and time. Formed by the refractive media focused on the retina of the eye image, and make the energy density of the retina is the cornea on the incident energy density increase from 104 to 105; Good monochromaticity, laser in the fun...[Detailed]

(a) a directional lightOrdinary light is light in all directions. To emit light travels in one direction, need certain condenser device fitted on the light source, such as the cars headlights and the searchlight is equipped with concentrated role reflector, the radiation light together in one direction. The...[Detailed]

Realize the population inversion, meet the threshold condition and resonant condition. The first condition of produce light of stimulated emission of radiation is a population inversion, is to put in the valence band in the semiconductor electron to the conduction band. In order to obtain ion inversion, usu...[Detailed]

Before talking about laser mechanism about the stimulated radiation. There are three kinds of radiation process in optical radiation,One is in the high energy particles spontaneously to the low-energy state transition, called the spontaneous radiation;The second is in the high energy particles under the exc...[Detailed]

Laser diode includes single heterojunction (SH), double heterostructure (DH) and quantum well (ve) laser diode. Quantum well laser diode has low threshold current, the advantage of high output power, is currently the market mainstream products. Compared with laser, laser diode has advantages of high efficie...[Detailed]

Laser life science research, diagnosis and laser treatment, the laser treatment is divided into: laser surgery, the weak laser biostimulation effect of non-surgical therapy and laser photodynamic therapy.[Detailed]
