Double frequency green laser pointer
The double frequency green laser pointer has higher efficiency. At night, even low-power green light can be seen by Rayleigh scattering from atmospheric molecules, and astronomers often use it to refer to stars and constellations. When excited by an energy source, the laser medium usually emits photons of specific spectral lines. The wavelength is determined by the different quantum energy levels or energy states of the material. Usually, most of the atoms in the medium are in the ground state. A small part will also exist in higher energies. Usually, these higher energy states are unstable, and electrons release this excess energy almost immediately in the form of photons and return to the ground state. To understand this, we must use the infographic (below the text) to carefully study the principles of semiconductor lasers. Every extreme laser pointer needs a power source, mainly simple batteries or rechargeable batteries, some of which can also be charged via USB. The core of the laser is a semiconductor diode, which produces photons, that is, light.

Selling laser pointers is very suitable for your meetings, hiking, climbing walls or creating sensational lighting effects, and the laser pointer can be seen by the naked eye no matter whether it is day or night. We provide you with laser pointers with different functions at a very low price. The biggest highlight of the laser pointer is its applicability in various places. The light indicator can be used not only for presentations in dark rooms, but also in classrooms during the day and the light beam is clearly visible. The green laser pointer is more powerful than the red laser pointer, at least 60 times brighter or more. Therefore, they are visible in the daytime and from a distance, which makes them more sought after by people. In complete darkness, the range of the green high powered laser pointer can reach about 12,000 feet! For people with pure power, especially young people aspire to have one. Another distinguishing feature of green laser pointers is that they are durable and almost usable.
