Generation of laser radiation by nanostructured solid active elements with selective optical nanoresonators formed in nanoporous aluminum oxide films

Abstract

The generation of laser radiation by a nanostructured solid active element with natural selective optical nanoresonator formed in a nanoporous aluminum oxide film activated with rhodamine 6G has been obtained for the first time. The lasing is characterized by high-quality radiation with the absence of a spontaneous component. Chemical deposition of noble metals leads to the formation of internal nanoresonator into the porous structure. This reduces generation threshold more than two fold.

SiO2 barrier layer influence on the glass composites with oxide nano films laser ablation destruction

“…The nano dimensional oxide films using for the efficient change in the instrumental glass details properties allows one to considerably expand the range of application for modified glass composites [1][2][3][4][5]. Nano films are applied to change of the optical characteristics -the increasing in the light transmission by the optical details or giving of the reflecting properties [1,4] to them.…”
