S1). Here, we report on formation of nanoprotrusions on the surface of a bulk crystalline silicon wafer under femtosecond-laser ablation with a donut-shaped laser beam. By breaking circular symmetry of the irradiating donut-shaped fs-pulse beam, a switch in geometry of the formed surface nanoprotrusions from regular to chiral was demonstrated. Liposuction is a plastic surgery technique that allows doctors to remove fat from patients. 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. Learn more with this simple guide, which include Lasers - Lasers produce concentrated light.

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 To obtain the ablation parameters, laser ablation experiments were carried out on dental hard tissues using Ti:Sapphire femtosecond laser (800 nm, 100 fs, 10 kHz).

2011-11-01 · The performance of femtosecond (fs) laser intrastromal ablation was evaluated with backscattering-mode adaptive-optics multiphoton microscopy in ex vivo chicken corneas. The pulse energy of the fs source used for ablation was set to generate two different ablation patterns within the corneal stroma at a certain depth.
