Resumen
Three laser resonators are demonstrated emitting at 1053 nm and pumped at 797 nm by volume Bragg gratingequipped diodes, achieving the highest reported efficiencies for Nd:YLF in a four-level system, to the best of our
knowledge. A peak output power of 880 W is achieved by pumping the crystal with a diode stack of 1.4 kW of peak
pump power. Funda????o de Amparo ?? Pesquisa do Estado de S??o Paulo (FAPESP) Comiss??o Nacional de Energia Nuclear (CNEN) Conselho Nacional de Desenvolvimento Cient??fico e Tecnol??gico (CNPq) FAPESP: 1710765-5 CNEN: 01342.002132/2020-75 CNPq: 308526 2021-0
