Laser assisted fabrication of micro-lens array and characterization of their beam shaping property

This paper demonstrates the formation of high-fill-factor plano-convex cylindrical and dome-type micro-lens arrays on fused silica glass surface using CO2 laser assisted reshaping technique. Cylindrical micro-lens array is fabricated by polishing the femtosecond laser engraved linear micro-gratings by a CO2 laser beam. Initially, a femtosecond laser beam has been irradiated on the surface of the fused silica glass samples to fabricate periodic...
