The utility model relates to a compact
laser module, which comprises a
resonant cavity shell, a pumping source and a cable flexible supporting piece, the
resonant cavity shell and the pumping source are connected with each other through an
optical fiber, a cable flexible supporting piece is arranged between the
resonant cavity shell and the pumping source, and the
optical fiber is connected with the cable flexible supporting piece. According to the utility model, through the arrangement of the autorotation connecting piece, the fixed connecting piece, the flexible connecting piece and other parts, and through the cooperation of the three parts, the cable flexible supporting piece can be bent, i.e., the maximum bending degree is 180 degrees, so that the pumping source can be arranged outside the resonant cavity shell, and meanwhile, the cable flexible supporting piece can be bent at the same time. The
optical fiber is supported to ensure that the optical
fiber is not broken, through arrangement of the resonant cavity shell, the cover plate and the autorotation connecting piece, the effect that the cable flexible supporting piece can rotate with the center of the movable groove as the circle center is achieved, the cable flexible supporting piece is matched with the flexible connecting piece, and the position of the pumping source can be flexible and changeable.
