As a result of the x-ray diffraction measurement on the ablated surface, the crystallinity of the surface is partially changed from a crystal structure into an amorphous one. 2014-02-11 · We investigated the initial modification and ablation of crystalline silicon with single and multiple Ti:sapphire laser pulses of 5 to 400 fs duration. In accordance with earlier established models, we found the phenomena amorphization, melting, re-crystallization, nucleated vaporization, and ablation to occur with increasing laser fluence down to the shortest pulse durations. The fundamentals of laser ablation process using ultrashort laser pulses are not still fully understood. Pulse duration of femtosecond laser pulse is shorter than electron-to-ion energy transfer time and heat conduction time in the sample lattice. Femtosecond laser ablation of enamel The surface topographical, compositional, and structural modifications induced in human enamel by femtosecond laser ablation is studied.

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.

2021-01-01 · Ablation plumes formed during femtosecond laser interaction with metals have been reported in previous studies , , , . A multicomponent ablation plume is formed on the target surface, including vapour-phase atoms in the front part of the plume, small clusters and droplets in the middle of the plume and liquid metal near the surface [26] , [50] .

Doctors can perform liposuction in several ways, including a laser-assisted procedure known colloquially as laser lipo. Unless otherwise noted, the Cornea surgery patients may experience some common complications after the procedure, including a minor issue that causes cloudy vision. Eye doctors use YAG lasers to treat this complication.

Dye-enhanced, plasma-mediated ablation of the skin is therefore a potentially advantageous approach to enhance topical/transdermal drug absorption.

However, this approach is accompanied by thermal damage to the nail tissue surrounding the laser radiation-created pore. In this paper, fluorescence microscopy has been employed to quantitatively evaluate thermal damage to the nail induced by laser ablation with 80 MHz, nanojoule, femtosecond pulses delivered via a hollow-core fibre.
