The porous optical film has higher threshold of laser-induced damage than densified films, for the study of mechanism of laser-induced damage of porous optical film with ordered pore structure. Porous anodic alumina (PAA) film with high transmittance on glass substrate has been prepared. Aluminum film was deposited on glass substrate by means of resistance and electron beam heat (EBH) evaporation...
The optical properties of tantalum oxide thin films fabricated by electron beam evaporation with ion assisted have been investigated. The as-deposited thin films are of good transmittance, of which the maxima is about 93%, close to that of the bare substrate; the refractive indexes are found to increase with the substrate temperature. The elemental composition and chemical bonding state in the as-deposited...
