A coupling device includes a fiber collimator, a wedge window pair and a plane window for coupling a light beam provided by a beam source to optical fiber. The fiber collimator is mounted to a base plate and includes a collimator lens, an end of the optical fiber being positioned at a focal point of the collimator lens. The wedge window pair is mounted to the base plate, and is configured to adjust the light beam to be parallel to an optical axis of the fiber collimator. The plane window is mounted to the base plate between the wedge window pair and the fiber collimator. The plane window is configured to align the parallel direction of the light beam with the optical axis of the fiber collimator.
