Disponível em: http://repositorio.ipen.br/handle/123456789/33067.http://repositorio.ipen.br/handle/123456789/33067We demonstrate a Nd:YLiF4 laser emitting at the 1053nm transition while side-pumped at 797nm by a VBG equipped diode. Initially, a plane-concave cavity is employed using a total internal reflection at the crystal pump face. The laser operated in QCW-mode and produced 68% of slope and 66% of optical efficiency with 67 W of peak output power, while having a multimode beam quality. These efficiencies are the highest ever reported for the Nd:YLF4 pumped at 800nm.1198007-1 - 1198007-5openAccessneodymium laserslaserssolid state lasersoptical pumpingdiode-pumped solid state lasersTexto completo de evento10.1117/12.26089670000-0002-9379-9530https://orcid.org/0000-0002-9379-9530
