Abstract

The coupling of a high-power，high-energy and narrow pulse laser unit with the optical fiber is important and of unique value in laser applications. Existence of the damage threshold in the fiber end face makes it very difficult to realize the coupling through lenses. In this paper was designed an umbrella shaped laser-fiber coupler by analyzing the mechanism of damage of an optical fiber and realized a coupling of a high-power (10MW) , high-energy (20mJ), narrow pulse (20ns) and high frequency electrooptical Q- switched Nd: YAG laser with a multimode optical fiber. Ihe coupling efficiency is over 80% .

Key words
