Laser Fabrication and Comparative Study of Planoconcave and Planoconvex Microlenses on Fused Silica and Sapphire

We report on fabricating planoconcave lenses using a picosecond 355 nm wavelength laser and a CO<sub>2</sub> laser. We also report the fabrication of the planoconvex microlens array on fused silica by patterned micromachining using a picosecond laser and reshaping using a CO<sub>2&...
