Abstract

PURPOSE:To obtain an optical fiber base material having uniform characteristics in the longitudinal direction by regulating the position and direction of a starting material spouting passage so that the luminous points of a beam of light intersecting the passage and a beam of light passing over the passage are superposed at the center of a depositing surface. CONSTITUTION:Starting materials for glass are allowed to spout out of inner tube 5 of burner 1 in a vapor state, and H2 gas and O2 gas out of outer tubes 6, 6', respectively. The resulting oxide powder is deposited on receiving stand 2. Stand 2 is moved in the arrow direction so as to keep the depositing surface at a fixed position to burner 1 at all times. A beam of light from light source 10 is irradiated on the surface of depositing surface B of deposite S, and a beam of light from light source 11 is passed over starting material spouting passage A and irradiated on surface B. The direction and position of passage S are then controlled so that the luminous points of the beam of light from both sources 10, 11 are superposed. Since the position and direction of passage S can be maintained correctly at all times, an optical fiber base material having uniform characteristics in the longitudinal direction can be obtd.
