本文研制了一种实用化石英光纤球形头。实验中采用大芯径石英光纤,把石英光纤的一端熔融拉锥并研磨成锥形端面,采用特殊助剂方法在其上面加入特殊的物质后研制成球形端面,并对所研制的石英光纤球形端面输出光功率进行测试。研究结果表明,球形光纤头的各个角度输出光能量较均匀,尤其是侧面输出光功率得到了很大改善,而且依据所研制光纤球形头工艺稳定,有实际应用的潜力,为光纤的进一步实用化提供了依据。 This paper developed a practical quartz optical fiber spherical head. In the experiment, a large core quartz fiber was used to fuse one end of a fused silica fiber into a taper end. A special additive was added to the quartz fiber to form a spherical end surface. End face output optical power for testing. The results show that the output power of spherical optical fiber is more uniform at all angles, especially the side output optical power has been greatly improved. Moreover, based on the stable optical fiber ball head technology developed and practical application, further practical application of optical fiber Provided the basis.
