Melasma is a challenging pigmentation disorder to treat, and although low-fluence 1064 nm picosecond ND-YAG lasers have shown potential for treating benign pigmented disorders, data on the use of this laser melasma treatment are currently insufficient. In prospective split-face study, twenty-four patients with face were enrolled randomly assigned receive one side either or PTP mode Q-switched l...

A double‐pulsed laser ablation (DPLA) method has been used to synthesize crystalline boron nanorods (BNRs), nanowires (BNWs), and bamboo‐like nanotubes (BBNTs) from bulk (BKB). q‐switched Nd: YAG operating at the first second harmonic wavelengths with 1064 532 nm is ablate a solid composite target doped 1% Ni Co in tube furnace flowing argon gas. Boron nanostructures form of BNRs, BNWs, BBNTs a...

BACKGROUND Long-pulsed Nd : YAG laser has been used in treating larger and deep-seated leg veins. OBJECTIVE This study investigated the effectiveness and safety of long-pulsed Nd : YAG laser to treat alae nasae and nasal tip telangiectasia. METHODS Twelve patients were evaluated in a prospective IRB approved study. They had a history of previous unsatisfactory treatments with pulsed dye las...

The present work aims to achieve pulsed laser deposition ofTiO2 nanostructures and investigate their nonlinear properties using z-scan technique.The second harmonic Q-switched Nd: YAG at repetition rate of 1Hz wavelength 532 nm with three different fluencies in the range 0.77-1.1 J/cm2 was utilized irradiate TiO2 target. products laser-induced plasma were characterized by utilizing UV-Vis absor...

STATEMENT OF PROBLEM The osseointegration of dental implant is related to their composition and surface treatment. Titanium zirconium (TiZr) has been introduced as an alternative to the commercially pure titanium and its alloys as dental implant material, which is attributed to its superior mechanical and biological properties. Surface treatments of TiZr have been introduced to enhance their os...

BACKGROUND According to the high prevalence of myopia in Taiwan, we analyze the adopted cataract extractions, identify predicting factors for postoperative vision, and to assess the incidence of retinal complications after Nd: YAG laser capsulotomy in high myopic eyes. METHODS One hundred and twenty-five eyes, which the axial lengths were longer than 26 mm, following cataract extraction were ...

A LIBS technique was used to investigate the antibacterial activity of calcium oxide nanoparticles (CaO NPs). CaO NPs were prepared using a Q-switched Nd: YAG pulsed laser with fundamental wavelength 1064 nm at different energies (400-600 mJ) and constant frequency (6 Hz). powder sample after being pressed into disc diameter 1 cm. Analyzing X-ray diffraction (XRD) showed crystalline structure N...
