Chemically Strengthened Slab Laser Glass with Optical Surface Quality


Slab laser glass was chemically etched to remove microcracks on the polished surface and increase the fracture strength. Xe lamp irradiation test showed dramatically high fracture strength for chemically etched surface compared to polished surface. However, the chemically etched surface is optically neither flat nor smooth. The new fabrication method, chemical polishing, was developed to get simultaneously both chemically strengthened and optically smooth surface.

The slab laser glass fabricated by the new method showed 2.5 times high bending strength as well as optical flat and smooth surface.
