A method of manufacturing a side-coupling structure, associated with coupling an aiming beam from an aiming beam fiber into a laser beam fiber, may include removing a coating from a section of the laser beam fiber and removing a coating from a section of the aiming beam fiber. The method may further include bringing the section of the aiming beam fiber in physical contact with the section of the laser beam fiber in order to create the side-coupling structure. The method may further include recoating the section of the laser beam fiber and the section of the aiming beam fiber in order to coat the side-coupling structure.
