odes for pumping solid-state lasers. Diode pumping of solid-state lasers is performed either by end or side-pumping geometries. As well known, end or longitudinal pumping of Nd:YAG lasers is the method for obtaining higher conversion efficiencies of pump-to-TEM.-laser outputs compared to side-pumpedDri727 发表于 2025-3-24 09:21:45

Sarah Ann Pintoof chemical species, but only few of them are directly emitted and considered as main pollutants. All the others are trace constituents, being nevertheless of outstanding importance for the chemical dynamics in the atmosphere. Since, e.g. smog situations do not only depend on the occurring emissionsDensity 发表于 2025-3-24 18:06:33
