A configuration of the water-jet guided pump for the fiber laser

摘要

The water-jet guided pump (WJGP) is newly proposed to solve the serious thermal effects in high power end-pumped fiber lasers. In this pumping scheme, the pumping light is coupled into the water-jet similar to an optical fiber. The light is guided by the jet and pumped into a following fiber. The experiment of WJGP double-clad fiber is carried out and the maximum coupling efficiency is 71.4%.
