1. Comparing the structure of laser equipment

　　在二氧化碳激光切割中，二氧化碳氣體是產生激光束的介質。然而，光學激光器是通過二極管和光纖電纜工作的。光纖激光系統將激光束泵入多個二極管，然后通過柔性光纖電纜傳輸到激光切割頭，而不是通過鏡子。這有很多優點，是裁斷床的尺寸。與氣體激光器不同的是，光纖激光器沒有限制。氣體激光器的反射鏡必須設置在一定的距離上。你甚可以在等離子切割床的等離子切割頭旁邊安裝一個光纖激光器，這不是co2激光切割的選擇。同樣，與同等功率的氣割系統相比，纖維的抗彎能力使系統顯得更加緊湊。

　　In carbon dioxide laser cutting, carbon dioxide gas is the medium to produce laser beams. However, optical lasers operate through diodes and fiber optic cables. The optical fiber laser system pumps the laser beam into several diodes and then transmits it to the laser cutting head through flexible optical fiber cables rather than through a mirror. This has many advantages, first of all, cutting the size of the bed. Unlike gas lasers, fiber lasers have no limitations. Reflectors of gas lasers must be set at a certain distance. You can even install a fiber laser next to the plasma cutting head of the plasma cutting machine, which is not the choice for CO2 laser cutting. Similarly, the bending resistance of the fibers makes the system more compact than that of the gas cutting system with the same power.

　　2. 比較電燈的轉換效率

　　2. Comparing the conversion efficiency of electric lamps

　　纖維切割技術重要和有意義的優勢應該是它的能源效率。光纖激光切割系統具有完整的固態數字模塊和單一的光纖激光設計，比co2激光切割具有更高的光電轉換效率。對于co2減排系統的每個動力單元，實際總利用率約為8% ~ 10%。對于光纖激光切割系統，用戶可以期望更高的功率效率，約25%30%。換句話說，光纖切割系統作為一個整體使用的能源大約是co2切割系統的三到五倍，將能源效率提高到86%以上。

　　The most important and significant advantage of fiber cutting technology should be its energy efficiency. The optical fiber laser cutting system has a complete solid-state digital module and a single optical fiber laser design, which has higher photoelectric conversion efficiency than the CO2 laser cutting. For each power unit of the CO2 emission reduction system, the actual total utilization rate is about 8%-10%. For optical fiber laser cutting system, users can expect higher power efficiency, about 25% to 30%. In other words, optical fiber cutting system as a whole uses about three to five times as much energy as CO2 cutting system, increasing energy efficiency to more than 86%.

　　3.對比切割效果

　　3. Contrast cutting effect

　　光纖激光器具有短波長特性，可以提高切割材料對光的吸收，并可以切割黃銅、銅等材料以及非導電材料。光束越集中，聚焦越小，聚焦深度越深，光纖激光器就能更快、更有效地切割較薄的材料。當切割材料厚度達到6mm時，1.5kw光纖激光切割系統的切割速度相當于3kW二氧化碳激光切割系統的切割速度。由于纖維切割的操作成本低于傳統的co2切割系統，這可以解釋為產量的增加和商業成本的降低。

　　Fiber laser has short wavelength characteristics, which can improve the light absorption of cutting materials, and can cut brass, copper and other materials as well as non-conductive materials. The more focused the beam, the smaller the focus and the deeper the focus depth, the faster and more effective the fiber laser can cut the thinner material. When the cutting material thickness reaches 6 mm, the cutting speed of 1.5 kW fiber laser cutting system is equivalent to that of 3 kW carbon dioxide laser cutting system. Because the operation cost of fiber cutting is lower than that of traditional CO2 cutting system, this can be explained as the increase of output and the decrease of commercial cost.

　　4. 維護成本進行比較

　　4. Maintenance cost comparison

　　在機器的維護上，光纖激光切割更加和方便。二氧化碳激光系統需要定期維護。鏡子需要維護和校準，諧振器需要定期維護。另一方面，光纖激光切割解決方案幾乎不需要維護。二氧化碳激光切割系統需要二氧化碳作為激光氣體。由于二氧化碳氣體的純度，空腔會受到污染，需要定期清洗。對于一個千瓦級的二氧化碳系統，每年少要花費2萬美元。此外，許多二氧化碳減排需要高速軸流式渦輪機來輸送激光氣體，而渦輪機需要維護和翻新。

　　In the maintenance of the machine, optical fiber laser cutting is more environmentally friendly and convenient. Carbon dioxide laser systems need regular maintenance. Mirrors need to be maintained and calibrated, and resonators need regular maintenance. On the other hand, fiber laser cutting solutions require little maintenance. Carbon dioxide laser cutting system needs carbon dioxide as laser gas. Because of the purity of carbon dioxide gas, the cavity will be polluted and need to be cleaned regularly. For a kilowatt carbon dioxide system, it costs at least $20,000 a year. In addition, many carbon dioxide emission reductions require high-speed axial-flow turbines to deliver laser gas, while turbines need to be maintained and refurbished.

　　從以上對比來看，雖然CO2的切割能力非常強，但是纖維在和成本上仍然占有較高的優勢。纖維所帶來的經濟效益遠遠高于CO2。在未來的發展趨勢中，光纖激光切割機將占據主流設備的地位。

　　From the above comparison, although CO2 cutting ability is very strong, but the fiber still has a higher advantage in energy saving and cost. The economic benefit of fibers is much higher than that of carbon dioxide. In the future development trend, optical fiber laser cutting machine will occupy the position of the mainstream equipment.
