It is also our first industrial-grade single-module 12000W fiber laser in China.It has excellent beam quality, the minimum BPP can reach 2. 5mm.mrad, the minimum output core is 75μm, and the core can be selected according to different applications. In addition, we have integrated the mature spot mode conversion technology into this laser, so that our 12000W has a variety of optional functions such as Gaussian beam, Tophat beam and circular spot beam, so as to meet the diverse application needs of customers. Moreover, the optical efficiency of the whole machine has reached more than 40%.
