1. Comparing the structure of laser equipment

　　在二氧化碳激光切割中，二氧化碳气体是产生激光束的介质。然而，光学激光器是通过二极管和光纤电缆工作的。光纤激光系统将激光束泵入多个二极管，然后通过柔性光纤电缆传输到激光切割头，而不是通过镜子。这有很多优点，是裁断床的尺寸。与气体激光器不同的是，光纤激光器没有限制。气体激光器的反射镜必须设置在一定的距离上。你甚可以在等离子切割床的等离子切割头旁边安装一个光纤激光器，这不是co2激光切割的选择。同样，与同等功率的气割系统相比，纤维的抗弯能力使系统显得更加紧凑。

　　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. 比较电灯的转换效率

　　2. Comparing the conversion efficiency of electric lamps

　　纤维切割技术重要和有意义的优势应该是它的能源效率。光纤激光切割系统具有完整的固态数字模块和单一的光纤激光设计，比co2激光切割具有更高的光电转换效率。对于co2减排系统的每个动力单元，实际总利用率约为8% ~ 10%。对于光纤激光切割系统，用户可以期望更高的功率效率，约25%30%。换句话说，光纤切割系统作为一个整体使用的能源大约是co2切割系统的三到五倍，将能源效率提高到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.对比切割效果

　　3. Contrast cutting effect

　　光纤激光器具有短波长特性，可以提高切割材料对光的吸收，并可以切割黄铜、铜等材料以及非导电材料。光束越集中，聚焦越小，聚焦深度越深，光纤激光器就能更快、更有效地切割较薄的材料。当切割材料厚度达到6mm时，1.5kw光纤激光切割系统的切割速度相当于3kW二氧化碳激光切割系统的切割速度。由于纤维切割的操作成本低于传统的co2切割系统，这可以解释为产量的增加和商业成本的降低。

　　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. 维护成本进行比较

　　4. Maintenance cost comparison

　　在机器的维护上，光纤激光切割更加和方便。二氧化碳激光系统需要定期维护。镜子需要维护和校准，谐振器需要定期维护。另一方面，光纤激光切割解决方案几乎不需要维护。二氧化碳激光切割系统需要二氧化碳作为激光气体。由于二氧化碳气体的纯度，空腔会受到污染，需要定期清洗。对于一个千瓦级的二氧化碳系统，每年少要花费2万美元。此外，许多二氧化碳减排需要高速轴流式涡轮机来输送激光气体，而涡轮机需要维护和翻新。

　　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.

　　从以上对比来看，虽然CO2的切割能力非常强，但是纤维在和成本上仍然占有较高的优势。纤维所带来的经济效益远远高于CO2。在未来的发展趋势中，光纤激光切割机将占据主流设备的地位。

　　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.
