In the simulation, the OLED was divided into 1 µm × 1 µm sections andPOLEDwas normalized to a value of 1. The OLED emission pattern was calculated using the same simulation as the outcoupling efficiency. We simulated the emission pattern of the PNPN-OLED emitting to parylene...
, recent studies suggest that optimising laser processing parameters can yield a uniform layer of η-Fe2Al5 IMCs at the interface between Fe- and Al- rich regions, free from problems like hot and cold cracks, ultimately contributing to improved strengths of up to 4 kN (105.3 N/mm2)11...
For each AISI 1070 L-PBF process condition with a high surface specific energy (SED > 7 J/mm2), the density was measured on three samples, and results were presented as the average value. During the processing of AISI 1070, the unmelted residual powder in the chamber after ...
Gold (Au), titanium (Ti) and nickel (Ni) were deposited on thin micro cover glasses (18×18 mm2, 120-170 μm-thick, Matsunami, Japan) by vapour deposition with precise control of the thickness to achieve three types of metal-coated substrates: Au (200 nm)/Ti (10 nm)/glass, Ti (...
The energy of the laser was varied from ≈250 mJ to ≈6 00 mJ, and the beam was focused to fractions of mm2, achieving laser intensities in the range of 1–10 GW/cm2. The graphite target (a disk obtained by cutting a pyrolytic graphite rod) was covered by few mm'...
At 72 h, the 350 and 500 μm pore size structured implants (538.1 and 512.4 cells/mm2 respectively) statistically show a higher cell density than the control group (418.5 cells/mm2). Meanwhile, the cell density of the 200 μm group increases to 499.6 cells/mm2...
The melting efficiency which takes into account Kerf is mathematically expressed [40]: σmelt= σcut·Kerf, (12) where σcut is the cutting efficiency (how many mm2 are cut with 1 Joule) (mm2/J); σmelt is the melting efficiency (mm3/J). The mathematical modeling of the laser thermal...
However, the power scalability of the OPA is limited by the available aperture size of the BBO crystals (typically ~20 × 20 mm2). On the other hand, a BBO OPA pumped by 800-nm pulses can easily produce a few-cycle IR pulse with a multi-mJ output energy. Since the maximum output ...

While an intensity between 10 and 100 W/mm2 [2,3] is usually sufficient, laser sources with an average power between 2 kW and 5 kW are necessary depending on the size of the area. When lasers were first introduced into production, CO2 lasers were the only affordable laser sources ...
