The 1.5th-generation"three-high/one-excellent"YDF specialty laser fiber
摘要
Abstract
For the development of high-end fiber lasers and breaking through the technical bottlenecks limiting the output power and performance improvement of fiber laser systems,the Joint-Innovation Center of High Power Fiber Laser Technology,Institute of Chemical Materials(ICM)of China Academy of Engineering Physics(CAEP),adopted the mode-tailoring fabrication process technology,theoretically designed and firstly fabricated the 1.5th-generation(1.5G)YDF specialty laser fibers,which are particularly suitable for 976 nm-LD end-pumping method(976-technology route)to effectively improve the threshold of mode instability(TMI)and significantly optimize the beam quality of laser output.Compared with currently widely-used 1.0G Yb-APS fiber,1.5G YDF specialty laser fiber shows about 20%improvement both in laser output power and beam quality.The 1.5G YDF specialty laser fibers fully demonstrate technical characteristics of"three-high/one-excellent"—high power,high efficiency,high TMI threshold,and M2 optimization—which can be selected by high-end customers in the industrial market and/or applied in high power laser fields.关键词
