WebApr 1, 2024 · We also confirmed that no ablation occurred when directly irradiating the fused silica or N-BK7 glass substrates. After contacting these substrates with 1 M aqueous CuSO 4 solution, effective etching occurred under a laser power density of around 2 × 10 8 W/cm 2 , and lots of cracks and chipping were generated when the power density …
WebFor the required 10 mm focal length, 0.8 µL of PDMS was pipetted on the top of the glass substrate, forming a µ-lens with 3.9 mm base diameter and 0.52 mm central height. An approximation to the ideal point shown in Figure 2 is very difficult, due to the low PDMS volume required, which compromises the reproducibility of the process. songs by martina mcbrideWebLaser scribing of fluorine-doped tin oxide coated on glass substrate in air and water.
