高功率双包层光纤激光器作为一种新型固体激光器,具有效率高、光束质量好、易于散热、结构紧凑等优点,与传统的气体和固体激光器相比,优势明显,在工业、国防、空间等领域具有非常重要的应用价值。这种基于包层抽运技术的光纤激光器,采用低亮度的二极管激光器作为抽运源,以稀土掺杂的特种新型光纤为工作介质,实现高亮度、高光束质量的激光输出,是高功牢固体激光的重要发展趋势之一。目
Compared with traditional gas and solid-state lasers, high-power double-clad fiber lasers have the advantages of high efficiency, good beam quality, easy cooling, compact structure and other advantages. They have obvious advantages in industry, national defense and space The field has very important application value. The fiber laser based on cladding pumping technology uses a low-brightness diode laser as a pumping source and a rare earth-doped special new optical fiber as a working medium to achieve high brightness and high beam quality laser output. One of the important trends of bulk laser. Head
