| Research Abstract |
Basic technologies of the phase coupled laser composed by 16 fiber laser modules were developed in this research. This number is the value that corresponds to twice the number reported with past papers. Coupling efficiency reached 94% in coupled 16-fiber-laser-modules. These technologies are high effective for high power fiber laser and precision machining. High resolution and practicable phase controlling technology was achieved by this research. As a result, high power fiber laser has been advanced by coexisting high beam quality.
