ABSTRACT:
A tunable CO.sub.2 gas laser is used to selectively heat various SiO.sub.2 -based materials to elevated temperatures while maintaining an active device region at relatively low temperatures, to, for example, induce densification and/or flow of the SiO.sub.2 -based material to round off sharp edges and stops.
