FUSED SILICA HAVING HIGH RESISTANCE TO OPTICAL DAMAGE

摘要

PURPOSE: A method is provided to render fused silica resistant to compaction caused by ultra violet laser beams and by fused silica optical members. CONSTITUTION: The method in a fused silica member that is desensitized to compaction caused by the long term exposure to UV laser beams. The invention includes a means to pre compact fused silica members using high energy radiation.
