Paper Abstract

A novel kind of domestic twins fiber that consisted of active unit and passive unit was researched in this paper. The slop efficiency of the twins fiber was observed via various laser amplification testing systems, which were respectively established with two different pump wavelengths and two different numerical apertures of pump output fiber. The effect of both pump wavelength and numerical aperture on the slop efficiency of the twins fiber was analyzed during the experiment. After the laser amplification testing system was optimized, the slop efficiency of the twin fiber increased from 72.1% to 82.1%. The numerical aperture of the pump output fiber would exert a distinct influence on the slop efficiency of the twins fiber. Simultaneously, the method to improve the slop efficiency of the twins fiber and decrease heat generating in high power fiber laser system was suggested.
