Abstract
Patente de Invenção:<B>"APARELHO E MéTODO PARA PRODUZIR UM FEIXE DE LASER APERFEIçOADO"<D>. Esta invenção refere-se a um feixe de laser aperfeiçoado útil em processamento de superfície de material e um aparelho para produzir o feixe de laser aperfeiçoado. O feixe de laser aperfeiçoado da presente invenção compreende uma distribuição de energia que é mais intensa nas regiões externas que na região central. A invenção inclui um aparelho que compreende elementos óticos alinhados para focalizar e/ou conformar um feixe de laser em um novo perfil útil em processamento de superfície de material. A invenção inclui ainda um método, de uso deste aparelho para focalizar e/ou conforme um feixe de laser para produzir Laser Induced Surface Improvements (Aperfeiçoamentos de Superfície Induzida por Laser), daqui por diante referido como "LISI".
