Pulsed laser ablation of hydroxyapatite in ethanol

Pulsed Laser Deposition of Hydroxyapatite Thin Films

Liquid-Phase Pulsed Laser Ablation

Crystallographic texture in pulsed laser deposited hydroxyapatite bioceramic coatings.

The orientation texture of pulsed laser deposited hydroxyapatite coatings was studied by X-ray diffraction techniques. Increasing the laser energy density of the KrF excimer laser used in the deposition process from 5 to 7 J/cm(2) increases the tendency for the c-axes of the hydroxyapatite grains to be aligned perpendicular to the substrate. This preferred orientation is most pronounced when th...

Interface kinetics during pulsed laser ablation

This work investigates evaporation kinetics — the relation between the surface temperature and pressure during excimer laser ablation. Nickel targets are ablated by excimer laser pulses in a laser fluence range between 1 and 6 J/cm2, with the upper limit exceeding the threshold of phase explosion (5 J/cm2). The surface pressure is determined with a polyvinylidene fluoride (PVDF) piezoelectric t...
