The traditional glass forming using laser ablation in air would produce many kinds of defects such as bulge, debris, crack and scorch. In this paper, we have applied the method of PDMS assisted laser processing to reduce the temperature gradient, heat-affect zone region for achieving crack-free glass ablation. The laser power of 15 W, PDMS thickness of 150 μm and scanning speed of 228 and 342 mm/s...
We have developed compact laser-pumped and discharge-pumped lasers operating at wavelengths of lambda=13.2 nm and lambda=46.9 nm respectively, and have used them in the demonstration of nanoscale full field imaging, nanopatterning, and nanoscale laser ablation. Using these new compact short wavelength lasers we have built two microscopes, using lambda=46.9 nm or lambda=13.2 nm laser illumination....
