Abstract

To investigate the practicability of a solar-directpumped fiber laser by using a parabolic dish concentrator,the solar power absorbed by the fiber laser and its absorption efficiency were calculated with numerical method based on the characteristics of solar spectrum in outer space.Results showed that it was realizable by taking such measures as using high inner-clad numerical aperture,appropriate rare-earth doped double-clad fiber and decreasing transmission loss of sunlight.In this paper,a new structure of multi-mode fiber array or parabolic dish concentrator array combination with tapered fiber bundles was proposed to enhance the solar pump power.
