基于主振荡功率放大(MOPA)结构的全光纤激光器无需空间光路调节,具有结构紧凑、工作稳定等优势,是高功率光纤激光器的重要发展方向。高功率光纤激光的国产化对于突破国外长期以来形成的价格垄断和技术封锁,实现具有自主知识产权的光纤激光器具有重要意义。
All-fiber laser based on the main oscillator power amplifier (MOPA) structure does not need space optical path adjustment, and has the advantages of compact structure and stable operation. It is an important development direction of high power fiber laser. The localization of high-power fiber laser is of great significance for the breakthrough of price monopoly and technology blockade established by foreign countries and realization of fiber laser with independent intellectual property rights.
