20.500.12556/RUL-190377 Obdelava stekla z nanosekundnim ultravijoličnim laserjem Glass processing with nanosecond ultraviolet laser Raziskali smo lasersko obdelavo stekla z nanosekundnimi ultravijoličnimi bliski. Pri izdelavi površinskih kanalov in podpovršinskih oznak smo spreminjali energijo posameznih bliskov, faktor prekrivanja preko hitrosti procesiranja in število prehodov laserja preko obdelovanega območja. Ocenili smo, da smo izboljšanje v gladkosti kanalov dosegli s počasnejšo obdelavo in povišano energijo, vendar smo slednjo omejevali glede na prisotnost stranskih učinkov ter ohranjanje globine. V notranjosti stekla smo izdelali sledi v bližini velikosti snopa v gorišču in ugotovili, da je vidnost najbolj povečana z njihovim mreženjem. Za uspešno reproduciranje 5 mm visokega 3D modela znotraj obdelovanca smo z namenom ohranitve podrobnosti obdelavo omejili zgolj na obrobje naloženih plasti. We have researched laser processing of glass with nanosecond ultraviolet pulses. While manufacturing surface channels and subsurface markings, the values of pulse energy, pulse overlap through processing speed and number of passes over the laser processed area were changed. We have assessed, that an improvement in the smoothness of the channels was achieved by slowing down the process and raising the energy, but the latter had to be limited based on the presence of side effects and preserving depth. Inside the glass we have produced traces close to the size of a focused laser beam and came to a conclusion, that visibility is best raised by their blending. To succesfully reproduce a 5 mm tall 3D model inside the workpiece while preserving its details, we have limited the processing to the perimeters of the stacked layers. laserska obdelava stekla ultravijolični nanosekundni bliski lom svetlobe absorpcija laserske sledi 3D označbe laser processing of glass ultraviolet nanosecond pulses light refraction absorption laser traces 3D markings true false false [G.
