In recent years, my country's laser industry has developed rapidly, especially in the field of domestic fiber lasers. Many businesses are pushing 10,000-watt pigtailed lasers. Is the higher the power of the fiber laser, the better? How is the fiber laser market?
In order to obtain a larger fiber laser output, such as a 10,000-watt fiber laser, it is an effective method to combine multiple medium-power fiber lasers, and the key component required is a fiber combiner. Therefore, for high-power fiber lasers, the thermal management technology in the combiner and the quality of the output beam after combining have become the keys to obtaining high-quality high-power fiber lasers in the industry. At the same time, most of the new application fields involved in high-power fiber lasers require high beam quality. To determine whether a high-power fiber laser is stable and reliable, and how advanced its technology is, it can be compared from this perspective.
High-power fiber lasers are mainly used for laser cutting and welding in the industrial field. Whether the higher the power, the better, many laser companies have proposed the concept of "limit power". They believe that in terms of laser cutting applications, the cutting process itself has a limit power. If the limit power is exceeded, the cutting quality and speed will no longer be improved. Instead, other lasers are used for processing, such as excimer lasers or carbon dioxide lasers. It is better in terms of cost and efficiency. If the actual power is less than the limit power, as the power increases, the cutting speed will increase accordingly; if the actual power is greater than the limit power, with the increase of power, the cutting speed will remain unchanged and will not improve; at the same time, the cutting effect will also be improved. There will be no change. The above point of view is considered from the limit power in industrial processing. Purely from the application of laser as a tool and heat source in laser processing, the higher the power, the stronger the processing ability.
In terms of application fields, high-power lasers are very suitable for military applications such as rail transportation, aerospace, shipbuilding, and ship welding. However, for high-tech enterprises, technology and product R&D investment is the largest cost. Category, need to invest the appropriate talent, funds, time. Companies that cannot supply some core components themselves need to purchase raw materials such as optical fibers, pump sources, beam combiners, gratings, circuit control systems, etc., and the cost is even higher. "To be or not to be, that's a question", and whether the higher the power of the fiber laser is, the better, this "good" is not a question with an absolute answer. The continuous breakthrough of technology, the localization of core components, the improvement of supporting equipment, and the development of market demand and application fields will all promote the development of fiber lasers and the transformation and upgrading of the manufacturing industry.
