High powered laser and photon energy can not interact with each other? Pointer?

Imagine the interaction of.High powered laser pointer collider is there, but not for high energy laser manufacturing. The design ideas of photon collider experiments is the electron positron collider based laser irradiation is a high-energy electron beam, resulting in a back to the process of inverse Compton scattering, photon emission extremely high energy collisions.

We all know that part of the sub hard scattering process in high powered laser pointer does not directly calculate the proton proton scattering scattering, but the calculation of a quark or gluon and another quark or gluon, part of a certain momentum x the probability density can be used to describe the parton distribution function.

Similarly, the distribution of high powered laser  pointer collider can have such a concept to describe the initial state. Of course the concept of electronic states is not practical, as the Delta (x-1) is good enough, but it can use this to make an unnecessary move; the amount of the initial distribution function to describe the photon.high powered laser pointer2

A simple calculation shows that for large high powered laser pointer PDF is very small, it is not difficult to understand clearly the bremsstrahlung photon radiation to become soft tend to focus on the small X area. This time the laser can play its role, although a single photon laser energy is very small.

The harm of high powered laser pointer is not reduced because it is homemade

Some people think I posted out of the laser classification is only applicable to the goods, high powered laser pointer made no difference. Indeed, you now own at home with laser, no one to ask for your label. However, laser damage should not because it is lower. The main requirements of the self-made problem is destructive the answer, he gave an absolutely destructive thing, also seems to encourage questions to do.high powered laser pointer1

I don’t know you are so destructive thing to do, he at home to disregard the safety of death is also not playing, playing the crime; but if you think “high powered laser pointer made nobody, holding on the road, the passers-by had residual playing dead, nature had changed.

Spider man has a famous saying, “With great power comes great responsibility.” when your ability to use this dangerous, do you know what you’re doing here. Why nuclear password box should be in the hands of the president, instead of one of his relatives, neuropathy? Is a truth. So, don’t know high powered laser pointer with his playing badly, messy residue, playing dead, is reckless.high powered laser pointer2

Obviously has more than 4 kinds of high powered laser pointer standard, even if the diffuse light may be permanent blindness, than Tianjin granny “gun” do not know where to go bad. If a bear children get the things into the street, I can easily see committing the crime of endangering public safety. “, causing serious consequences, can be sentenced to ten years imprisonment, life imprisonment or death.”

To do with the high powered laser pointer, to the LCD TV, invisible (no red dot) what principle?

Because the LCD TV color bright, ordinary red pen, or the kind of low power high powered laser pointer the copycat, can not be satisfied. For liquid crystal display, its composition is completely transparent to the flow characteristics of liquid crystal, the light transmittance is high, then the reflected light is small, it is difficult to identify.

In order to prevent the interference of external light source imaging, a low reflective liquid crystal display technology in liquid crystal glass, which is special treatment on the glass surface, the reflectivity of external light in around 1%, almost no high powered laser pointer will be reflected into the eye, to see the red dot.high powered laser pointer2

Two opaque pen tightly clamped together side by side, a two pen in the middle position above the light parallel to the high powered laser pointer will see the color stripes. Because light has the same frequency, the diffraction phenomenon.

In a spherical mirror in the room, people inside, high powered laser pointer issued by the parallel light reflected by the spherical mirror, the first reflector is very small, the scattering is not obvious. After several reflections of spherical space filled with reflected light. The past is reflected in a mirror to see his again, a trivial detail of yourself. Themselves, finally become blurred. Very small and can be ignored. It can not see their own. As an infinite number of spherical polyhedra.

When high powered laser pointer and AR to achieve the perfect fusion, laser projection will become a catalyst, with which you can enter into a new environment in the new

High powered laser pointer dazzling, but the head of the fourth generation display laser projection technology can also display the aura, ruthless role of science and technology circle in recent years. Known as the “excellent quality” of it, the pace of technological change has been more than Moore’s law. In the face of sharper screen, more expressive color, more interactive true immersive experience, the user for the laser projection display performance requirements have been satisfied.high powered laser pointer1

As a new generation of display technology, high powered laser pointer has the following advantages: the first advantage is geometry, double color high-definition laser. High brightness, easy to eye geometric resolution limit of the large screen display. Existing high-definition TV is 1280 * 720,4K, the future can be achieved 8K display on the big screen.

Because the high powered laser pointer line, up to the edge of the chromaticity diagram, high color saturation; laser spectrum is rich, can constitute the greatest chromaticity triangle, the existing display color gamut coverage increased by 3 times. In three color laser projectors as an example, the performance of more than 90% of the human nature can identify the color.high powered laser pointer3

High powered laser pointer is the reverse display holography, essentially by forming a three-dimensional image in the air or the special three-dimensional lenses. Unlike flat screen projection by only two-dimensional surface perspective, shadows and other effects to achieve three-dimensional, holographic projection technology is really showing 3D images, can different side view images from any angle of 360 degrees”
