Abstract:
1. A method of producing a titania-doped silica glass boule, the method comprising the steps of: providing a substantially homogeneous titania-doped silica glass rod, the titania-doped silica glass rod having a titania content of between about 1 and about 10 wt %, the titania-doped silica glass rod being substantially non-porous; feeding the titania-doped silica glass rod into a furnace, the furnace having a glass collection surface therein, wherein the titania-doped silica glass rod is softened in the furnace to form a softened titania-doped silica glass, and the softened titania-doped silica glass is deposited on the collection surface, thereby forming a softened titania-doped silica glass mass; and cooling the titania-doped silica glass mass to produce the titania-doped silica glass boule.
