| Research Abstract |
We have studied the porous-silica AR coating used for UV lasers in conjunction with ion-injection and surface treatment. Spectral transmittance, surface roughness and laser-induced damage were measured.
The experimental results over two years has been completed and published in this end of March, 1992.
