Jan 22, 2019 For high laser fluences, the ablation of the heated material occurs several tens of picoseconds after the laser pulse is absorbed. Coherent Fig3.

The research explores use of femtosecond laser to clean surface of Ti-6Al-4V alloy. The laser ablation threshold was determined from either depths or diameters of laser-induced craters. Both methods are expected to give the same results; however, it was found that ablation threshold can

For enamel, the maximum ablation efficiency was 0.009 mm3∕J at a fluence of 7.59 J∕cm2.Ablation efficiency of the femtosecond laser on dentin and enamel is closely related to the laser fluence and may reach a maximum when 2007-11-02 · Nanoparticle formation by femtosecond laser ablation. J Perrière 1, C Boulmer-Leborgne 2,3, R Benzerga 2 and S Tricot 2. Published 2 November 2007 • 2007 IOP Publishing Ltd Journal of Physics D: Applied Physics, Volume 40, Number 22 2019-04-12 · The presented GHz femtosecond laser source is used with a galvanometric scanner to perform ablation experiments on copper, aluminum, and stainless steel. Specific ablation rates of 0.7, 2.3, and 1.4 (mm 3 /min)/W are reached. We demonstrated a method of fabricating three-dimensional (3D) metal structures in hydrogels with good conductivity by using femtosecond laser ablation and electroplating. The hydrogel containing Ag+ was first ablated by a femtosecond laser to form microchannels with an entrance achieving surface and then sandwiched between the anode and cathode to operate electroplating.

Dye-enhanced, plasma-mediated ablation of the skin is therefore a potentially advantageous approach to enhance topical/transdermal drug absorption. The combination of a fiber laser and a HC-NCF, capable of emitting and delivering femtosecond pulsed, visible light, may permit a compact poration device to be developed. Abstract: Thermodynamics effects generated by femtosecond laser ablation are very important. In this work, the numerical simulation of high-energy femtosecond laser ablation especially the electro-phonon coupling coefficient influence of high-energy femtosecond laser ablation on metal target was studied. Interaction of intense ultrashort laser pulses (120 fs at 795 nm) with polymer based composites has been investigated. We have found that carbon filled polymers exhibit different ultrafast ablation behaviour depending on whether the filling material is carbon black or carbon fiber and on the polymer matrix itself.

2021-02-01 · Femtosecond laser ablation of metals has been investigated for over 30 years. Compared with longer pulses, femtosecond laser ablation indeed has lots of advantages, including the finer interaction spot beyond the optical diffraction limit , the smaller heat-affected zone (HAZ) , and the higher energy deposition rate , .

2002-02-22 · The mechanism of ablation of solids by intense femtosecond laser pulses is described in an explicit analytical form. It is shown that at high intensities when the ionization of the target material is complete before the end of the pulse, the ablation mechanism is the same for both metals and dielectrics. 2016-01-15 · In the theoretical studies on femtosecond laser ablation of copper, most of the works focus on the use of a two-temperature (TTM) model , , , , or a hydrodynamic model . On the other hand, experiments with single- or multi-shot ablation of copper under different laser parameters have also been presented, e.g., laser fluence [1] , [9] , [10] , [11] , incident angle and polarization [12] , and pulse duration [13] .
