Abstract

Abstract

Using the fiber laser spectral beam combining technology, the limitation of the output power of a single fiber laser due to nonlinear factors can be broken, and a higher power laser output can be realized. Combing the development history of spectral beam combing technology and analyzing its current situation, principle, advantages and disadvantages, and combining with our research, we have designed a portable 3-channel combining system. By optimizing the entire combining system, three high power narrow linewidth fiber lasers of 1055 nm, 1070 nm and 1085 nm were combined to achieve a high-power laser output of 9650 W, with combincotion efficiency of 92%, and beam quality M² of 1.7. The future dichromatic mirror spectral beam combining is also prospected.
