ftr-raman spectra of human dental enamel, both laser-irradiated and untreated, are reported. spectra are compared with hydroxyapatite. it is evident that unlike the co2 laser, the nd/yag laser does not induce any chemical change in dental enamel.

introduction: the efficacy of erbium-doped yttrium aluminum garnet (er:yag) laser for root debridement in comparison with curettes has been the subject of many recent investigations. considering the possibility of chemical and ultra-structural changes in root surfaces following laser irradiation, this study sought to assess the effects of scaling and root planing (srp) with curettes and er:yag ...

in this paper metal-assisted chemical etching has been applied to pattern porous silicon regions and silicon nanohole arrays in submicron period simply by using positive photoresist as a mask layer. in order to define silicon nanostructures, metal-assisted chemical etching (mace) was carried out with silver catalyst. provided solution (or materiel) in combination with laser interference lithogr...

The laser, an acronym for light amplification by stimulated emission of radiation, is a source of nearly monochromatic, coherent, electromagnetic radiation that propagates as a beam. The chemical laser is a type of laser system that is driven by the release of energy during a chemical reaction. Chemical lasers are usually large, high power devices that integrate chemical delivery systems, a sup...
