Method and system for laser cleaving optical fibers

Abstract

A method and system for laser cleaving an optical fiber. The method includes applying a non-diffracting beam to the optical fiber to create a plurality of perforations therein by pulsing and scanning the non-diffracting beam across the optical fiber. The perforations form a perforation plane in the optical fiber across which the optical fiber is separated to form a cleaved fiber end face. The system includes a laser, an optical assembly that receives a laser beam from the laser and outputs the non-diffracting beam, and one or more translation stages configured to scan the non-diffracting beam across the optical fiber such that the plurality of perforations are created in the optical fiber to define the perforation plane. Penetration depth of the non-diffracting beam is controlled by adjusting one or more parameters of the non-diffracting beam to avoid damage to the core region of the optical fiber.
