Thermal lensing-induced dynamic beam evolution and damage behaviors in a 1 kHz, 521 mJ nanosecond Ho:YLF MOPA system

A high-power, high-energy 2-μm Ho:YLF MOPA[A1] system delivering 521 mJ pulses with a pulse width of 20.3 ns at a repetition rate of 1 kHz was demonstrated using a polarization beam combining technique. To the best of our knowledge, this represents the highest pulse energy report...

Oral multi-niche microbiota and age stratification: a novel strategy for precision screening of periodontitis

Abstract Background: periodontitis is a prevalent chronic inflammatory disease driven by oral microbiota dysbiosis, with profound oral and systemic impacts that impair healthy aging. Conventional screening methods are invasive and delay early detection, while microbiota-based str...
