Crack-free high-aspect ratio holes in glasses by top–down percussion drilling with infrared femtosecond laser GHz-bursts

چکیده
Abstract We report novel results on top-down percussion drilling in different glasses with femtosecond laser GHz-bursts. Thanks to this particular regime of light – matter interaction, combining non-linear absorption and thermal cumulative effects, we obtained crack-free holes aspect ratios exceeding 30 sodalime 70 fused silica. The are discussed terms inner wall morphology, ratio speed.

High-aspect ratio nanochannel formation by single femtosecond laser pulses
Single femtosecond pulsed laser damage can be confined radially to regions smaller than the focus spot size due to the highly nonlinear mechanisms for energy absorption and ablation in transparent dielectrics. Along the propagation axis, however, we show that channels can be machined much deeper than the Rayleigh range of the laser focus. Using focused ion beam cross sections and acetate imprin...
متن کاملMicro-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 کاملExperimental Study in the Process Parameters in Laser Percussion Drilling
In order to service and grow in the present day of global competition, every manufacturing concern focuses mostly on two factors i.e. productivity and quality. Laser drilling is a popular non-traditional machining technique for producing large numbers of cooling holes of various sizes (less than mm diameter) and angles in modern aerotech components such as turbine blades, injector nozzles, and ...
متن کاملModels for Solidification and Splashing in Laser Percussion Drilling
This paper studies systems of partial differential equations modelling laser percussion drilling. The particular phenomenon considered in detail is the ejection of the thin layer of molten material. This thin layer is modelled as an inviscid flow between the fluid surface and fluid/solid interface, both of which are unknown moving boundaries. Through a regular asymptotic expansion, the governin...
