Fully automatic fiber laser cutting machine fiber laser has 'very obvious advantages such as flexible processing'? If fiber laser is used for mulberry processing, should the double-clad fiber be directly used for transmission, or the light output from the double-clad Coupling into a single-mode fiber? So what are the advantages and limitations of fiber lasers? The structure of fiber lasers enables it to have high beam quality under high power, and it is possible to achieve high efficiency! This is its advantage! However, it does not explain The current IPG and the light of other companies. Lasers have these advantages, and the market has explained that they do not have these advantages. Principle of CO2 Laser Generator Carbon dioxide laser used its wavelength of 10.6um in 1964. Because this is a very efficient laser with a conversion efficiency of 10% as a commercial model, CO2 lasers are widely used in laser cutting, welding, drilling and surface treatment. As a commercial application laser up to 45 kilowatts, this is the current strong material processing laser. The carbon dioxide laser is a molecular laser. The main substance is the carbon dioxide molecule.

The full-automatic fiber laser cutting machine can show a variety of energy states, depending on the shape of its vibration and rotation. The basic energy network is shown in Figure 1. The mixed gas in carbon dioxide is a plasma (plasma) formed by a low-pressure gas (usually 30-50 Torr) caused by the release of electrons. As Maxwell-Boltzmann's law of distribution says, in plasma, molecules exhibit multiple states of excitement. These will present a high-energy state (00o1) which appears as an asymmetric swing state. When colliding with a hollow wall or naturally radiating, such molecules will accidentally lose energy. Through natural emission, this high-energy state will drop to a symmetrical swing form (1Do0) and emit photons (a light beam with a wavelength of 10.6um) that may travel in any direction. Occasionally, one of these photons will propagate down the cavity of the optical axis and will swing in the resonance mirror. In general, the working substance of a carbon dioxide laser is a mixture of carbon dioxide, hydrogen, and nitrogen. Nitrogen acts as a buffer gas and its molecules resonantly transfer stimulating energy to carbon dioxide molecules. Because the relaxation level (01110) is the bottleneck, the role of helium is to transfer energy to the level (01110) to helium atoms as a heat sink. CO2 laser is a relatively important gas laser. This is because it has some prominent advantages: it has relatively large power and relatively high energy conversion efficiency. A general closed-tube CO2 laser can have a continuous output power of several tens of watts, which is far more than other gas lasers, and a lateral flow electrically-excited CO2 laser can have a continuous output of hundreds of thousands of watts. In addition, the lateral atmospheric pressure CO2 laser has reached a higher level in energy and power from the pulse output, which is comparable to solid-state lasers. The energy conversion efficiency of CO2 lasers can reach 30-40%, which also exceeds that of general gas lasers. Second, it uses the vibration-rotational transition of CO2 molecules to form a mixture of carbon, hydrogen, and nitrogen.
