The lithography ion-exchange method of producing the gradient index micro-cylinder lens with gradual focus is presented. The lens is developed for the coupled shaping of the pump beam of side-pumped disk fiber laser, its main purpose is to make the LD beam which coupled into the ring disk container and the radial of the ring disk container have a certain angle, and ensure that all the pump beams couple into the interior of the ring disk container through the thin slit of the side. The micro-cylinder lens with different shapes can be obtained by the special designs of ion-exchange windows. The focused spot of the parallel beam passed through the lens is a special curve with required setting. Consequently, the lens also adapt to other applies with gradual focus. The experimental results coincide with the design.
