Paper Abstract

The result shows that the fusing atmosphere and heat treatment process have different affluence on the laser induced damage threshold (LIDT) by 355nm and 248nm laser pules. As for the fused silca, the atmosphere and the temperature during the fuseing and heat treatment process contributes to the changing of structure and micro-composition. For high power 355nm laser pules, the affluence of H2 during the fusing process is benefical to reduced the destructive probability, the LIDT-values is about 20-22.2 J/cm2; But for the 248nm laser pules ,the highest LIDT-values is about 8-10J/cm2 of the fused silca fused with surplus O2 atmosphere. In order to improve the laser damage character, the heat treatment process is one of the effective way for the fused silica. We have investigated the peculiar heat treatment process with O2 atmosphere by 1100℃ can boost the LIDT to 28.2 J/cm2 and 13 J/cm2 by 355nm and 248nm laser pules, while the process time is not as long as better.
