Disponível em: http://repositorio.ipen.br/handle/123456789/17798.http://repositorio.ipen.br/handle/123456789/17798We present the results of measuring metallic molybdenum ablation threshold in the 30 femtoseconds regime. The measurements were performed in atmosphere and vacuum, resulting in values equal to 1.6 TW/cm2 3.8 TW/cm2, respectively. This values difference can be credited to a plasma etching that helps the ablation in the atmosphere case.openAccessablationpulsesbreakdownlasersTexto completo de evento10.1364/LAOP.2010.ThD3https://orcid.org/0000-0003-0092-9357https://orcid.org/0000-0003-1371-7521https://orcid.org/0000-0001-7762-8961
