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 کاملMicro-hole drilling and cutting using femtosecond fiber laser
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. The shape and morphology of the holes were characterized and evaluated with optical and scanning electron microscopy. Debris-free micro-holes with good roundness and no...
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...
متن کاملResearch on the Inner Wall of the Blind Hole Drilling Device
This article describes the structure and the working principle of the blind hole drilling device, by application in the production practice proves its feasibility. At present, we commonly used electrical discharge machining and welding method to solve the problem. However, these methods have the low processing efficiency, low manufacturing precision and high cost defect. This paper developed an...
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...
