Artigo IPEN-doc 30102 Results in highly-efficient side-pumped Nd:YLF lasers2023 - 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.Artigo IPEN-doc 30049 Modern diode pumped solid state lasers2023 - 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.Artigo IPEN-doc 21608 Optical properties of mice skin for optical therapy relevant wavelengths: influence of gender and pigmentation2015 - SABINO, C.P.; DEANA, A.M.; SILVA, D.F.T.; FRANCA, C.M.; YOSHIMURA, T.M.; RIBEIRO, M.S.Artigo IPEN-doc 20911 Double-beam-mode-controlling diode-side-oumped Nd>YLF laser with near 60% efficiency2015 - DEANA, ALESSANDRO M.; WETTER, NIKLAUS U.Artigo IPEN-doc 20894 Influence of pump bandwidth on the efficiency of side-pumped, double-beam mode-controlled lasers: stablishing a new record for Nd:YLiFsub(4) lasers using VBG2015 - WETTER, NIKLAUS U.; DEANA, ALESSANDRO M.Artigo IPEN-doc 20785 Propriedades ópticas da pele de camundongos (630-905 nm): influência da idade e massa corpórea2014 - SABINO, C.P.; DEANA, A.M.; SILVA, D.F.T.; FRANÇA, C.M.; YOSHIMURA, T.M.; RIBEIRO, M.S.Artigo IPEN-doc 20751 Treating metabolic sundrome's metaflammation with low level light therapy: preliminary results2014 - YOSHIMURA, TANIA M.; KATO, ILKA T.; DEANA, ALESSANDRO M.; RIBEIRO, MARTHA S.Metabolic syndrome comprises a constellation of morbidities such as insulin resistance, hyperinsulinemia, atherogenic dyslipidemia, dysglycemia and obesity (especially abdominal). Metabolic alterations are observed in major insulin target organs, increasing the risk of cardiovascular diseases, type-2 diabetes and therefore mortality. Tissue alterations are characterized by immune cells infiltrates (especially activated macrophages). Released inflammatory mediators such as TNF-α induce chronic inflammation in subjects with metabolic syndrome, since inflammatory pathways are activated in the neighboring cells. The intra-abdominal adipose tissue appears to be of particular importance in the onset of the inflammatory state, and strategies contributing to modulate the inflammatory process within this adipose tissue can mitigate the metabolic syndrome consequences. Considering the low level light therapy (LLLT) recognized benefits in inflammatory conditions, we hypothesized this therapeutic approach could promote positive effects in modulating the inflammatory state of metabolic syndrome. That being the scope of this study, male C57BL/6 mice were submitted to a high-fat/high-fructose diet among 8 weeks to induce metabolic syndrome. Animals were then irradiated on the abdominal region during 21 days using an 850 nm LED (6 sessions, 300 seconds per session, 60 mW output power, ~6 J/cm² fluence, ~19 mW/cm² fluence rate). Before and during treatment, blood was sampled either from the retroorbital plexus or from tail puncture for glucose, total cholesterol and triglycerides analysis. So far our results indicate no alterations on these metabolic parameters after LLLT. For further investigations, blood was collected for plasma inflammatory cytokine quantification and fresh ex vivo samples of liver and intra-abdominal adipose tissue were harvested for immunohistochemistry purposes.Artigo IPEN-doc 20363 Record efficiencies and power scalability in diode-side-pumped Nd:YliFsub(4) lasers using double-beam mode-controlling2014 - WETTER, NIKLAUS U.; GESKUS, DIMITRI; DEANA, ALESSANDRO M.Capítulo IPEN-doc 13197 Pulse-energy-enhanced, strongly modulated Er:YLF laser for medical applications2008 - DEANA, ALESSANDRO M.; WETTER, NIKLAUS U.; BALDOCHI, SONIA L.; RANIERI, IZILDA M.Artigo IPEN-doc 20204 Power scaling of a side-pumped Nd:YLF laser based on DBMC technology2014 - WETTER, NIKLAUS U.; DEANA, ALESSANDRO M.
