Abstract

Based on the specialty designed linear-core-array fiber, a laser beam shape convertor has been proposed and demonstrated. The experimental and theoretical results shown that a multi beam with the peak power distributed in a linear array have been obtained at the end of the linear-core-array fiber and the output beam shape depend on the coupling condition and the supermodes propagation distance along the linear-core-array fiber. This device transfers the laser shape from a Gaussian beam to a controlled linear array beam. It could be used in industry for manufacturing or medicine applications.
