Existing CO 2 In the laser-heat-source fusion tapering method, the equipment is relatively complex; the diameter of the laser spot reaches hundreds of micrometers (or more), if the melting point of the optical fiber (1800 ℃ or so) is to be reached, a high-power (20W or more) laser needs to be selected, so that the energy consumption is relatively high; the laser used is mostly continuous light, which is more unfavorable for overcoming the hysteresis of the vibrating mirror (in the actual scanning process, the scanning vibrating mirror has certain hysteresis, namely, when the vibrating mirror moves to the left end and the right end of the scanning area, the acceleration of the vibrating mirror disappears instantly, and the laser beam is not stopped at the moment, so that a laser dense area is formed at the edge of a hot area, an overhigh temperature is generated, and even physical damage is caused to an optical fiber), and a smoother hot area range is unfavorable. The utility model proposes to use high-frequency pulse CO 2 The laser is used as a heat source to manufacture the fused biconical optical fiber, and the technology shows the advantages which are not possessed by many flame technologies, and has important value for manufacturing high-quality fused biconical optical fibers.
