Paper Abstract

A method for injecting a high peak power multimode laser beam into an optical fiber has been developed. The design minimizes the peak irradiance on the fiber's entrance face and reduces its dependence on the laser's mode structure and the system alignment. A simple lens and a specially designed kinoform (or binary optics element) operate together to transform a 5 mm diameter laser beam into two concentric ring foci that fit on the 400 micrometers diameter fiber face.
