The energy density formula for laser point scanning is as follows: (4.5)q=Wv×H where q is laser energy density, the unit is J/mm2, W is laser power, H is laser spot diameter, and v is scanning speed. Laser energy density plays a decisive role in SLS forming, and its size is ...
The average liquid thickness d (μm) was then calculated as d = V μL /A mm2 . In absence of rotation, the error in estimating A is low as the liquid is clearly encircled also when photographing the sample perpendicularly to the support (Figure 5(a)). If the liquid reaches borders ...

typically 10 mm2, and they did not have to be focused to produce sufficient photon energy to induce a change in tissue, as every photon in the beam could by itself produce a change. As a consequence, my own thoughts and those of Trokel were to use large beams to reprofile the ...
where ‘Cp’ is the capacitance across the sample (μF), ‘d’ is the thickness of grown crystal (mm), ‘A’ is the cross-sectional area of the sample (mm2), ‘εo’ is the free space permittivity (8.854 × 10−12F m−1), and ‘tanδ’ is the dissipation factor. The dielec...
measuring diastolic arterial blood pressure and calculating trophic coefficient from formula TC= LBCS*FCN/ Pdiast, where LBCS is the linear blood circulation speed in supratrochlear artery, FCN is the functioning capillary number in 1 mm2 of vision field counted when examining microcirculation stream ...
In particular, to reach the values of Ii and Fi required for ICF FI, the ion (proton) beam must be extracted from the ion source of a large area (Sis ∼ a few mm2) and then strongly Radiation Effects & Defects in Solids 259 focused to increase the beam intensity and fluence by a...
However, according to an experimental invest- igation on laser thinning of few-layer MoS2 (even under a power density of mW/mm2) by Castellanos-Gomez et al.20, the stability and robustness issues of TMDs becomes a significant problem if exposed to high power laser illumination. Unlike ...
The spot size of the ns rectangularly shaped laser beam was about 24 × 6 mm2 with almost a top hat intensity distribution, while the fs laser beam spot size was about 2 × 3 mm2. The laser fluence could be varied between 0 and 130 mJ/cm2 and between 0 and...
The saturation intensity, modulation depth, and nonsaturable loss of CsPbI3 were 117.1 mW/mm2, 2.62%,%, and 1.33%. The saturation intensity, modulation depth, and nonsaturable loss of CsPbI3-Au were 135.3 mW/mm2, 4.17%, and 3.66%. 2.2. Properties of CsPbI3 QDs Saturable Absorber The ...
