Results in highly-efficient side-pumped Nd:YLF lasers
2023 - PRADO, FELIPE M.; FRANCO, TOMAS J.; VIEIRA, TARCIO de A.; DEANA, ALESSANDRO M.; WETTER, NIKLAUS U.
Here we present resents advancements in Nd:YLF lasers, achieving record-breaking efficiency and output energies. In Q-switched operation, we obtained output energy of 41.2 mJ with peak power of 46 MW. Furthermore, we achieved a near quantum-defect slope efficiency of 78.2%, the highest reported for Nd:YLF lasers. We also present efficient 1314 nm laser emission.
Modern diode pumped solid state lasers
2023 - WETTER, NIKLAUS U.; PRADO, FELIPE M.; VIEIRA, TARCIO de A.; DEANA, ALESSANDRO M.
A brief review of the advances in diode-pumped, Neodymium-doped, high-efficiency lasers is presented, showing how different configurations were able to achieve extremely elevated slope efficiencies, close to the quantum limit, while demonstrating excellent beam quality.
68% slope efficiency Nd:YLF laser with 91 W of peak power
2022 - PRADO, FELIPE M.; VIEIRA, TARCIO de A.; WETTER, NIKLAUS U.
We demonstrate two highly efficient Nd:YLiF4 lasers, achieving the highest efficiencies for Nd:YLF side-pumped at 800 nm.
Near quantum limited slope efficiency Nd:YLF4 laser
2021 - VIEIRA, TARCIO de A.; PRADO, FELIPE M.; WETTER, NIKLAUS U.
We report on a Nd:YLF4 laser diode-side-pumped at 863 nm, resulting in 75% slope efficiency and 13.8 W of CW output power.
