Embodiment
Like Fig. 1, optical fiber outgoing end 1 is provided with disperse means layer 2, and said disperse means layer 2 is an arcuation, covers optical fiber end 1, and is fixed as one with optical fiber end 1.
The manufacturing approach that the utlity model has the optical fiber exit end of diffusion is: apply disperse means at optical fiber end 1, like Fig. 2, through arc discharge the optical fiber end 1 that has applied disperse means is heated then; Optical fiber end 1 is vertically set between the electrode, like Fig. 3, and the quartz generation thermal response of optical fiber end 1; The quartz material softening transform that is heated forms the arcuation lens under action of gravity, the disperse means layer 2 of covering makes it have diffusion; And heating makes disperse means and fiber optic materials be melt into one; Difficult drop-off, cooling forming after heating is accomplished, the optical fiber exit end that obtains having diffusion.Perhaps optical fiber end 1 is heated through arc discharge, optical fiber end generation thermal response, the quartz of end is at high temperature softening; Form the arcuation lens, cooling forming after heating is accomplished, the optical fiber end after processing applies disperse means then; Through arc discharge the optical fiber end that has applied disperse means is heated once more; Make disperse means and fiber optic materials be melt into one, form disperse means layer 2, thus the optical fiber exit end that obtains having diffusion.The direct projection light of processing back optical fiber outgoing end face is effectively blocked; Emergent light is the disperse shape; The disperse degree of emergent ray changes along with the variation of the radius-of-curvature of optical fiber exit end arcuation lens, and the size of the radius-of-curvature of optical fiber exit end arcuation lens can be controlled through processing technology.
In the arc discharge heating process, the distance and the angle of electrode 3 and optical fiber end 1 during through the adjustment discharge, and discharge time, the radius-of-curvature of the arcuation lens that the adjustment disperse means form.Optical fiber end apart from the distance of electrode by as far as closely; The machining shape of its end is just like the shape from (a) to (d) among Fig. 3; Also can make the machining shape of end become the shape to (d) by (a) discharge time from short to long, and the radius-of-curvature of promptly corresponding arcuation lens is descending.And hope behind the coating disperse means that discharge time is short as far as possible; Avoid end shape to produce sag by gravitate first, also avoid disperse means in the quartz of fusion, to flow in addition, make that coating is inhomogeneous; And angle can influence the temperature field distribution between tip electrodes; Directly influence the selection of discharge time, angle is more greatly that the distance of electrode and optical fiber end is long more discharge time far away, otherwise discharge time is short more.Corresponding needed radius-of-curvature is selected suitable discharge time, distance and angle according to mentioned above principle.
The current value of arc discharge is a stable parameter; Under the state that distance, angle, the time when discharge is all fixed; Energy when acting on the optical fiber end heating is also than stable with the laser thermal source; Then the radius-of-curvature of arcuation lens also is fixed on same state thereupon, has guaranteed the stability of product quality bills of materials performance.The radius-of-curvature of the arcuation lens that disperse means form is relevant with heating-up temperature and heat time heating time; Because current value and discharge time are accurately to adjust; So radius-of-curvature also can realize accurate adjustment and control, thereby the disperse degree of emergent light also is under control.And the mode through external heat source is processed optical fiber, causes the damage to optical fiber itself in the time of can avoiding with laser irradiating fiber processing end face.
The utility model utilizes between the electrode and discharges, and promptly the arc discharge mode is processed, even add man-hour at a large amount of optical fiber, the laser emitting state of optical fiber exit end is that the disperse degree can be not uneven yet.And the user uses optical fiber under the prerequisite of the state that can know the optical fiber end laser emitting.The disperse means that use be higher than 1500 ℃ Powdered mineral compound as fusing point; Selection for disperse means is that those skilled in the art are confirmable; Also have on the existing dispersion fiber on the optical fiber exit end after the processing and bond one deck disperse means as scattering particle with inorganic bond; Disperse means generally adopt metal oxide, and disperse means commonly used have titania.
Disperse means require fusing point to be higher than 1500 ℃; Be because approaching with the fusing point of quartz material; Thereby avoid also not softening at disperse means quartz material when heating; And disperse means take place to flow with regard to having begun thawing, cause the disperse means local accumulation, produce the coating inequality and then cause the uneven phenomenon of disperse effect; Powdered then the assurance can evenly apply, and be easy to use, can not look like again simultaneously liquidly just do not producing flow phenomenon under the situation of heating after the coating, causes applying uneven, influences the disperse effect.And the boiling point of liquid is lower, be easy under the also not softening situation of quartz, just vapored away, and the shortcoming of solid is to be unfavorable for even coating that inconvenience operates.
