The multi-direction firing of the optical fiber has been required to induce wider damage zone during the laser-assisted surgery. The optical fibers tend to have poor machinability because of its hardness and brittleness. In this study, we employed the ECDM to fabricate the tip of the optical fiber in cone-shape. The con-shaped tip made the multidirectional emission of the light at the distal end of the fiber. The result showed that the lower electrolyte concentration enhanced the surface quality. The optimal concentration of electrolyte was 15% to make high quality surface of optical fiber tip in this experimental condition. When the voltage was more lower, surface quality had been become better. The suitable voltage was 30V for the effective process time.
