Abstract
The invention relates to an opposite-emitting type optical fiber coupling auxiliary regulating device and a coupling method, which are used for coupling space laser beams to optical fibers. The device has a structure that a laser diode, a collimation lens, a half-wave plate, a diaphragm, a coupling lens and an optical fiber connector are coaxially and sequentially arranged on one base, the light-emitting surface of the laser diode is positioned on the front focal surface of the collimation lens, and the center of the optical fiber end surface of the optical connector is positioned in the focus of the coupling lens. The invention has the characteristics of simple structure, convenient use and operation and accurate and reliable coupling.
