A method for injecting a high peak power multimode YAG 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 {mu}m diameter fiber face.
