Abstract

in some applications, we need a Laser beam to form a special pattern. For example, we need a ring pattern laser beam for correcting Cornea in Ophthalmology experiment. In this paper ie introduce a method to create a ring pattern by use of a muitimode fiber. The arrangement is very simple that we create different diameter ring pattern by adjusting the fiber angle with corresponding to incident light rays or by changing different distance that is away from the output end of the fiber.
