Bright laser illuminates the world
In a dense gas plasma, short laser pulses propagate in a relativistic self-trapping mode, which can effectively convert laser energy into accelerated electrons. This state maintains the effective load and maximizes the total charge of accelerating electrons, thereby providing a large amount of electron induction accelerator radiation. 3D intracellular particle simulations show how this mechanism triggers X-ray generation with 0.1-1 MeV photon energy, low divergence, and high brightness. The results show that the 135 TW laser can be used to generate x 10^{10} photons with energy greater than 10 keV, while the 1.2 PW Laser pointer can generate about 10^{12} photons in the same energy range. The conversion efficiency of laser to gamma energy is as high as 10^{-4}3 ×1010> 10101210-4 For high-energy photons, keV, the conversion efficiency of X-rays in the entire keV range is estimated to be a few tenths of a percent.

Bright laser light source. The biggest advantage of the laser light source is that its color is very pure. In theory, the three-color laser light source is the light source with the best color performance at present, and it can make the displayed picture achieve almost perfect color performance. In addition, it can also achieve high brightness, and you don't need to turn off the lights and draw the curtains like projectors in the past when watching movies indoors. At the same time, the life of the laser light source is very long, which is also a prominent feature of the laser light source.Laser display technology has a wide range of applications. It can be used not only on TVs, but also for movie playback in commercial theaters. In addition to curtains, laser projection can also project images onto other objects. For example, the large-scale water curtain picture of Beijing Olympic Forest Park is made with laser display technology.
