摘要：

The light from a semiconductor laser is coupled efficiently into a tapered hemispherical-end optical fiber obtained by drawing in an arc discharge. The maximum coupling efficiency of 83 percent is achieved for the graded index fiber having a 60-μm core diameter. Permissible transverse displacement for a 1-dB decrease of coupling is about 19 μm.
