Comparison of different fiber laser cutting machines
Fiber laser cutting machine Working principle of fiber laser cutting machine Comparison of CO2 and fiber laser generator Nowadays, many companies are using laser cutting machines, laser die machines, and laser engraving machines. Do you know what is most important to laser equipment? Lasers. So what is the difference between CO2 lasers and fiber lasers? At present, CO2 lasers are the mainstream laser processing lasers, followed by lamp-pumped solid-state lasers, followed by fiber lasers for small and medium power. The data shows that the sales volume ratio of fiber lasers, lamp pumped solid-state lasers and DPL lasers in the processing field is 4:3.1:2.9; but the average sales prices of high-power CO2 lasers, lamp pumps, optical fibers, and DPL (diode pumped) are respectively It is 150,000 US dollars, 65,000, 29,000, and 22,000. At present, fiber lasers have not achieved 'very obvious advantages of high conversion efficiency and very good beam quality.' According to relevant data, the SPI 200-watt fiber laser used by Guangzhou Industrial Technology Research Institute is not fast for cutting 1 mm thick steel plates, 1.5 mm It can’t be cut, but according to an imported 500-watt lamp pump laser in Chongqing, it can cut 3 mm steel plate at a power of 300-400 watts; according to a 2006 LFW newsletter, a 1000-watt fiber laser cuts 0.5 mm steel plate The speed is much higher than that of CO2, and it is far inferior to CO2 when cutting 3 mm. This urgently shows the fact and basis that a fiber laser is not accepted by the high-power processing market! Fiber laser has 'very obvious advantages such as flexible processing'? If the fiber laser is used for mulberry processing, should the double-clad fiber be directly used for transmission, or the double-clad output light will be coupled into the single-mode fiber? So what are the advantages and limitations of the fiber laser? The structure of the fiber laser I have the ability to achieve high beam quality under high power, and it is possible to achieve high efficiency! This is its advantage! However, it does not mean that the current IPG and other company's light lasers have these advantages. The market has explained that they do not have it. These advantages.
Fiber laser cutting machine CO2 laser generator principle 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. Carbon dioxide laser is a kind of molecular laser. The main substance is carbon dioxide molecule. It can express 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.
