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...

Micro-hole drilling and cutting in ambient air are presented by using a femtosecond fiber laser. At first, the micro-hole drilling was investigated in both transparent (glasses) and nontransparent (metals and tissues) materials.

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 کاملParametric Study Of Hole Taper In Laser Micro-Drilling Of Copper Sheet
Laser beam machining is a thermal energy based non-contact type advanced material processing technique which can be applied for almost all materials. Nowadays there is an increasing trends towards miniaturization of various components used in different applications like MEMS, photonics, microelectronics, robotics, bio-medical devices, etc. which needs micro-machining. Use of laser microdrilling...
متن کاملProbing embryonic tissue mechanics with laser hole drilling.
We use laser hole drilling to assess the mechanics of an embryonic epithelium during development-in vivo and with subcellular resolution. We ablate a subcellular cylindrical hole clean through the epithelium and track the subsequent recoil of adjacent cells (on ms time scales). We investigate dorsal closure in the fruit fly with emphasis on apical constriction of amnioserosa cells. The mechanic...
