The integrated CNT-based fiber device is realized by sandwich- ing a ~2 mm2 sample between two fiber connectors, as shown in our previous report48. Theoretical modeling. We numerically simulated the pulse formation and evolution in the laser cavity with circulating pulse. The modeling ...
The areal energy density (Ea, J/mm2) takes into account the scanning speed and hatching space in Eq. (2):(2)Ea=Pv∙s The linear energy density (El, J/mm) is the basic density consider the single melt track in Eq. (3):(3)El=Pvwhere P is the laser power (W), v is the ...

S1). Dimensions of the samples equaled ~17 × 6 mm2 (width×height) with thicknesses ranging from 25 μm to 2 mm. During irradiation, samples were submerged into water, ethanol, or polyethylene glycol 300 (PEG) approximately 10 mm below the liquid surface. The most ...
(1)E(J/mm2)=P/dV In Equation(1), P stands for laser power in W, E for laser energy in J/mm2, V for scanning speed in m/s or mm/s, and d for laser beam or spot diameter. Based on Equation(1), it can be seen that there is a direct relationship between energy density and...
LIBS involves focusing a pulsed laser beam with an irradiance of at least 10 MW/mm2 onto a solid, liquid, or gaseous target. The intense photon flux breaks down the target material resulting in a plasma. The excited electronic states in the plasma emit light at characteristic wavelengths, ...
