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), will spontaneously transition to a low energy level laser welding machine supply in the absence of external action, the 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. 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, and low energy level than in the low atomic number density, it is because in level with the level of the size of atoms, the density of which increases E decreases exponentially, This is the famous Boltzmann distribution. Seen at 20 ℃, almost all of the hydrogen atoms in the ground state, make atom light emission, energy must be provided outside excited states of atoms arrive, so the ordinary light emission is broad contains two processes stimulated absorption and spontaneous radiation. In general, the energy radiated by this source of light is not strong, with emission in all directions, but the energy dispersion of the fiber laser marking machine is mainly composed of a laser, vibration lens, marking cards of three parts, the use of fiber lasers production of laser marking machine, laser welding machine good beam quality, the output of the center of 1064nm laser welding machine price, the whole life of around 100,000 hours, compared to other types of laser marking device last longer laser welding machine products, electro-optic conversion efficiency of over 28%, compared to other types of laser marking machine 2% to 10% conversion efficiency advantages of large, energy-saving and environmental protection and other aspects of performance is outstanding.
