As long as there are no metal shielding obstacles between the emitter

As long as there are

no metal shielding obstacles between the emitter and receiver of RF green laser pointer with remote control.
Electron can absorb or release energy from one to the step is moved to another level. For example, when the electronic absorption of a photon [2], it can be from a lower step moved to a higher

energy level (Figure 2). Similarly, one located in the high-energy bands e will transition to a lower energy level (Figure b) by emitting a photon. In these processes, the electronic absorption or

release of the photon energy is always the energy difference between these two bands are equal. Photon energy determines the wavelength of light, therefore, the absorption or release of light with

a fixed color. RF green laser pointer with remote control usually has higher costs.
Figure diatomic electronic transition process. When the atoms within the electron is at the lowest possible energy level, the lowest energy of the atoms, we call the atom in the ground state.

Figure 1 shows the carbon atoms in the arrangement of the electronic ground state situation. When one or more electrons at a higher level, we call the atoms in the excited state. I said before, the

electrons through absorption or release of transitions between energy levels. Transition can be divided into three forms: spontaneous absorption - Electronics by absorbing photons from the low-

energy step to move to high-energy bands (Figure 2 a). Spontaneous emission - Electronic spontaneously through the release of photons from the high-energy step to move to a lower energy level

(Figure 2b). But RF green laser pointer with remote control has no directivity.
By stimulated emission of radiation - photons launched into substance-induced electrons from the high-energy step to move to low-energy bands, and the release of the photon. Incident photon and the

release of photons have the same wavelength and phase, this wavelength corresponds to the energy difference between two energy levels. A photon-induced atomic emission of a photon, and finally

becomes two identical photons (Figure 2c). The schematic of the ruby laser. The laser is basically generated by the third transition mechanism. Figure III shows the principle of the ruby laser. It

consists of a flash, the laser medium and two mirrors.
