Paper Abstract

This paper mainly studied the structure of high power pump combiner. Pump combiner is one of the key components of high power fiber laser and fiber amplifier. The ability to conduct high power of pump combiner is often influenced by the heat dissipation structure. The faster the heat dissipates the higher power the combiner conducts and the higher power fiber laser the combiner can be applied in. We made a pump combiner with the help of a conical quartz tube and the heat dissipation structure of the combiner can send away the lights that the combiner leaks so that the heat accumulation in the combiner can be avoided. The experimental result shows that when the pump power reaches 3000W the temperature of the combiner is about 28℃ which indicates that the heat dissipation efficiency of the structure is high.
