Abstract

PURPOSE:To manufacture a glass base material with a low impurity content for laser of high performance by forming a porous glass body contg. Nd2O3 by a vapor axial deposition method while feeding fine particles of a neodymium compound soln. to a high temp. reaction section and by treating the glass body at a high temp. CONSTITUTION:Vapor phase starting material prepared by mixing SiCl4 as orincipal starting material with a dopant for controlling refractive index distrubtion such as GeCl4,PCl3 or BBr3 is fed to a torch 6a from a feeding pipe 7a together with H2, O2, He, etc., and an Nd compound soln. converted into mistlike particles with an ultrasonic oscillator 11 is also fed to the torch 6a together with Ar. On the other hand, SiCl4 as vapor phase starting material is fed to a torch 6b from a feeding pipe 7b. These materials are decomposed with the flames 8a, 8b of the torches and deposited on a starting substrate 2 as fine particles of oxide glass. Simultaneously, by pulling up the substrate 2 while rotating it, a porous glass base material 4 is formed. This material 4 is heated to about 1,400-1,500 deg.C in a gaseous mixture of He with Cl2 and converted into transparent glass by defoaming.
