Common sources emitting laser source (such as lights, flames, sun, etc. luminescence) is due to the material when subjected to external energy (such as solar energy, electricity, heat, etc.) the role of electrons in atoms will absorb external energy from low energy level transition to the high energy level, that atoms are excited. The excitation process is a "stimulated absorption" process. High energy level of electrons in a very short lifetime (typically 8 to 10 seconds), in the absence of external action under spontaneously transition to a low energy level, will produce light (electromagnetic) radiation transition. This radiation is called spontaneous emission. Atomic spontaneous emission process is a completely random process, light-emitting atoms each process independent, unrelated, that the radiation emitted in the direction of the light is random shooting in all directions, while not the phase, the polarization state is also different are not the same. Because there is an excitation level width laser engraving machine, so the frequency of the emitted light is not a single, but there is a range. Under normal conditions of thermal equilibrium, the number of atoms in a high energy level on the density of the laser engraving machine equipment, low energy level than in the low atomic number density, it is because the number of atoms in level when the magnitude of the density is increased with the energy level E The index decreased laser engraving machine manufacturers, which is famous for the Boltzmann distribution. Seen at 20 ℃, almost all of the hydrogen atoms in the ground state laser engraving machine supply, to make atomic light, must reach the outside world to provide energy excited states of atoms, so common is the inclusion of a broad luminescence stimulated absorption and spontaneous emission two a process. In general, the energy radiated by this source of light is not strong, with emission in all directions, but the energy is dispersed with the rapid development of optoelectronic technology, laser engraving technology range more widely, carving precision more to be higher. Effect of laser engraving four most fundamental elements are: engraving speed, laser power, engraving precision materials. On a specific material, such as to achieve a certain effect engraving, requires a certain energy absorbed laser energy should be seen as a material that absorbs the laser energy = laser power / engraving speed. Simply put, is to improve the laser energy absorbed by the material, they should raise or lower the laser power engraving speed, as to say which method depends on the final material and the final carving effect. In general, users will avoid the high and low speed, because it would reduce production efficiency. In fact, not only affects the efficiency of engraving engraving speed, precision carving also because they have a very big impact.
