Fiber laser is a laser cutting machine is the core component, in general, it has played a significant effect on the cutting laser cutting machine. When choosing laser cutting machine, fiber laser customers are very focused brand, even the life of the module integrated manner. Well, today on the high-energy 30000mw laser pointer to tell you about the fiber laser modules.
Fiber laser modules are divided into single-mode and multimode, in cutting applications, a focused spot has a great influence on the cut quality, relatively small core single-mode lasers, beam quality is better than multi-mode, energy distribution Gaussian distribution, the highest energy density in the middle, three-dimensional figure is a sharp mountain-like circle.
Multimode lasers compared to thicker core, single-mode beam quality to be worse compared to the distribution of energy as compared to the average number of single-mode light spot, a three-dimensional image inverted cup from the edge steepness of view, than multimode many steep single-mode.
1mm sheet cutting speed multi-mode single-mode than 20% higher, the visual effect is almost, but 2mm start, the speed advantage of the gradual decline from the beginning of 3mm, both speed and effect, the advantages of high-power multimode green laser pointer speed and effectiveness is very obvious It reflected. So the advantages of single-mode in the sheet, multimode advantages planks, single mode and multimode not mutually comparable value, is a fiber laser configuration, like a car, cars for the road, suitable for cross-country mountain but cars also run mountain, cross country and road run, so choose multimode fiber laser in the end depends on the actual end-user or single-mode processing needs.
So single-mode and multi-mode, how do we choose?
High Energy Laser suggestions: differentiate from the power level, the lasers 1000W or less because of the energy itself is not high, mainly in favor of the sheet processing of material thickness, and therefore within the single-mode 1000mw green laser 1KW configuration is in line with the actual market situation, more than 1KW of power to take into account the laser Bohou. From the entire industry in terms of processing, improve processing quality is a rigid demand, is not compromise, so a lot of high-power single-mode laser selection will not be considered to be the quality assurance process for the first!
At the same time, the single-mode core is generally smaller, which means the same power of the laser light energy transfer in which single-mode core carry more, the material is a challenge, but when cutting highly reflective material, high intensity reflection laser light emitted overlay, if the fiber material is less than the tolerance will be very easy to "burn core", while the core material life is also a challenge! So many laser manufacturers in the high-power fiber 500mw green laserconfigurations still use multimode Configuring!
