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 spontaneously under the action of the transition to a low energy level laser welding machine in Shandong, will produce light (electromagnetic) radiation transition. This radiation is called spontaneous emission. Atom spontaneous emission process is a completely random process, light-emitting atoms each process independent, unrelated laser welding machine price, that the radiation emitted in the direction of the light is random shooting in all directions, the other did not phase, polarization state is also different. Since the excitation energy level has a width, the frequency of the emitted light is not a single, but a range. Under normal conditions of thermal equilibrium, at a high energy level on the atomic number density, than in the low energy level of the low atomic number density laser welding machine supply, this is because the size of an atom in the energy level when the number density increases with the energy level E index decreases, which is famous for the Boltzmann distribution. Seen at 20 ℃, almost all of the hydrogen atoms in the ground state laser welding machine, make atom light emission, energy must be provided outside excited states of atoms arrive, so the ordinary generalized contains two light emission is absorbed and the spontaneous emission processes stimulated by . In general, the radiation energy of this light source is not strong, with emission in all directions, so that more energy is dispersed by laser cutting level of the laser beam emitted by the laser reflection mirror becomes 45 ° vertically downwards The laser beam, focused by a lens after, at the focal point together into a very small spot in the focal spot of the laser power density will be up to 10 ^ 6 ~ 10 ^ 9W / cm ^ 2. At its focal point of the workpiece by the high power density of the laser spot irradiation, will produce local temperature of 10000 ° C or more, so that the workpiece instantaneous vaporization, coupled with the auxiliary cutting gas vaporized metal blown off, thereby cutting through the workpiece into a very small holes, with the movement of CNC machine tools, linking numerous holes to be cut in the shape became. Due to the frequency of the laser cutting is very high, so each hole connection is very smooth, cut out of the product finish high.
