【摘要】 用熔拉法、腐蚀法、管腐蚀法、熔拉-腐蚀法、激光消融法等制备了光纤探针,对其外形进行了分析比较。熔拉法制作的探针,锥形过渡区细长,并且获得的探针锥角不大(8°～35°)。腐蚀法与管腐蚀法可以使探针的锥形过渡区短,损耗小,锥角大(15°～65°),但在制备更大的锥角光纤探针时,表面开始变得粗糙。拉伸-腐蚀的方法制作光纤探针存在一个变锥度区。激光消融腐蚀法容易获得大锥角的探针,并且表面光滑。更多还原

【Abstract】 The optical fiber probe is prepared with the melt-pulling etching,tube etching,pulling-etching and laser ablation method.By the experiments,the shapes of fiber probe are analyzed and compared.It shows that the cone-shape transition region of probe by the melt-pulling is slight and the probe cone angle is not big(8°～35°).The method of etching and the tube etching may cause the probe with the short cone-shape transition region,less loss,and the cone angle is bigger(15°～65°).But when the much bigger cone angle optical fiber probe is prepared,the surface becomes rough.Probe by the pulling-etching has an variable area of the changing cone angle.Probe by the laser ablation is easy to obtain the big cone angle,and the surface is smooth.更多还原
