Recent Specialty Fiber Research at Corning towards High-Power and High-Brightness Fiber Lasers

摘要

This paper reviews and presents the recent specialty fiber research and development conducted at Corning Incorporated towards high-power and high-brightness fiber lasers. These include the fabrication of all glass-composition, high-NA, Yb-doped double-clad laser fibers, and also of double-clad single-polarization laser fibers for further improved brightness in laser beam quality through innovative fiber designs. These have led to the 1st all-glass, high N A, Yb-doped high-power double-clad fiber made by an all-vapor-phase fiber-preform process in the world, and also the high-brightness, single-polarization double-clad high power laser fiber.
