| 英文摘要 | Fiber laser has the advantages of high light beam quality，high efficiency, and excellent heat elimination to generate high power laser, and thus can be used as the light source of the new generation laser machines. This dissertation primarily discusses the assemblage technology of the high-power all-fiber laser. Furthermore, it will introduce several virtual instruments specifically designed for the assembly work of the fiber laser. All the work will be beneficial to industrialized production of fiber laser. The first chapter introduces the application, current industry situation and core technology of the high-power all-fiber laser. Besides, this part briefly introduces the development of intelligent instrument based on virtual instrument technology, and its application requirement in the assembly work of the fiber laser. The second chapter introduces the experimental desktop type prototypes and integrated cabinet type prototypes. We calculate the distribution of the power loss with the experimental data, and discuss the thermal effect and other problems we meet in the assembly work of the prototypes. The latest prototype can generate 1040W laser. The third chapter introduces modularization designed prototype of the high-power all-fiber laser，which using domestic pump laser diode. This prototype can generate 1033W laser, with the beam quality factor M2 of 1.45. The fourth chapter introduces several virtual instruments specifically designed for the assembly work of the fiber laser. To illustrate how a virtual instrument works, this part gives a detailed account of the laser diode automatic testing systems and the high-power all-fiber laser protection and control system. Besides, this part also briefly introduces several other applications designed for the fiber laser. The fifth charter sums up the products of my assembly work of the high-power all-fiber laser. |
