... Abstract Direct laser machining in sub-micron scale patterning at a surface of material remains a challenging task though the laser machining has been widely applied in various application. A photonic nanojet becomes a promising way to solve the problem by involving near-field focusing of light...

... resistance. In this study, we propose a new laser heat treatment method to produce high-quality and high-accuracy shafts with high efficiency, low cost and low environmental impact. We will also develop a technique to derive the appropriate laser irradiation conditions quickly and systematically for shafts...

... tissue play very important roles. In this research, mist of glycerophosphoric acid calcium aqueous solution was applied on the laser irradiated area. As result, micro texture including Ca and P elements was generated on the Ti-6Al-4V-ELI alloys surfaces. When laser was irradiated, glycerophosphoric acid...
