Micro-hole drilling with femtosecond fiber laser
In this paper, micro-hole drilling in ambient air is presented using fs fiber laser (750 fs & 1030 nm). Micro holes were fabricated in both transparent (glasses) and non-transparent materials (metals and tissues). Hole shape and morphology was characterized and evaluated with optical microscope and scanning electron microscopy (SEM). Debris-free micro holes with good roundness and no thermal da...

متن کاملComparative Study of Hole Taper in Nd : YAG Laser Micro - drilling of Advanced Engineering Materials
The present study investigates the relationships and parameter interactions between three controllable variables (lamp current, pulse frequency and air pressure) on hole taper in micro-drilling operations, in order to assess the effect of the different process parameters and also material properties in laser micro-drilling operations. Micro-drilling experiments have been conducted for Gamma-Tit...

متن کاملMicro-Drilling of Polymer Tubular Ultramicroelectrode Arrays for Electrochemical Sensors
We present a reproducible fast prototyping procedure based on micro-drilling to produce homogeneous tubular ultramicroelectrode arrays made from poly(3,4-ethylenedioxythiophene) (PEDOT), a conductive polymer. Arrays of Ø 100 µm tubular electrodes each having a height of 0.37 ± 0.06 µm were reproducibly fabricated. The electrode dimensions were analyzed by SEM after deposition of silver dendrite...
