Ourlife depends on a variety of special substance and magic, these things aremostly our artificial body, mainly in the process of widely used laser is themost characteristic, we often use the laser for a variety of activities, laserapplication is extremely widespread. A lot of times, laser protection windowmanufacturers have found that a lot of people tend to lack the fullunderstanding of laser light in the process of using lasers. Beam quality isthe lifeline of high energy laser system, completes the beam quality is morethan a link of science and engineering, in the laser technology chain upstream,midstream and downstream of the technical difficulties and problems of the stabilityof whole system elements, comprehensive expression of the characteristic is thecore for the target on the laser intensity.
Highbrightness is one of the main features of the laser. The physical effects of alaser beam on an object, such as heating, melting, forming a plasma andproducing neutrons. And this is determined by illumination. We're going to saythat monochromatic brightness is the same as that of a photon, and thatbrightness is one of the surface features of the laser, which is the essence ofthe photon degeneracy. Second, the brightness of the laser, the brightness ofthe light source and illumination of the object The so-
called brightness isshort for surface brightness, is actually light surface per unit area of lightpower in a certain direction. The brightness of the light source in a directionis defined as 2 B dPdsd eos body (1) cutting dp is a shiny surface burning andproduct yuan ds with the normals of the sand into the direction of the Anglewithin the solid Angle d mouth zhang sent out by the luminous flux, also knownas light power or send out light energy per unit time Can say that the benefitsof laser is much larger than the disadvantages. Although the laser has a veryserious radiation hazard, it brings us a lot of benefits, and we hope thatpeople will face the use of laser light. The laser protection window tells youthat if you do your laser protection correctly, then many of the laser sideeffects can be completely avoided.
