Coupling device for high power laser beam transmitting optical fibers

摘要

A fiber optic coupling device for coupling two optical fibers transmitting a high power laser beam is disclosed. In one embodiment, the device comprises a first lens to collimate the beam delivered by one of the optical fibers and a second lens to focus that collimated beam onto the end of the other fiber for injection therein and continued transmission of the power laser beam through the second fiber.
