高功率光纤激光器在工业加工、材料处理等领域有着广泛的应用。目前,国际上全光纤结构单模激光输出功率已达到10kW量级,而基于国产器件的全光纤激光器仍停留在百瓦量级。研究并实现基于全国产器件的高功率光纤激光器,对于提高我国在光纤激光器领域的研发和生产实力、打破国外技术封锁和产品垄断,具有重要的意义。 High-power fiber lasers in industrial processing, materials processing and other fields have a wide range of applications. At present, the output power of single-mode laser with all-fiber structure in the world has reached the level of 10kW, while the all-fiber laser based on domestic devices still stays in the order of one hundred watts. Research and implementation of high-power fiber lasers based on the national devices have great significance for improving the R & D and production capabilities of our country in the field of fiber lasers and breaking the foreign technological blockade and product monopoly.
