We have deposited hydroxyapatite (HAp) films on Ti substrate by pulsed laser deposition using KrF excimer laser. We used HAp targets sintered at temperatures of 500, 700, 900 and 1100 °C with densities between 1.5 and 2.4 mg/mm 3 . SEM images of the

A new method for high-quality hydroxyapatite (HAp) coating is developed, the laser-assisted laser ablation method. In this method, two lasers are used. One is used for ablation of a HAp target. The other, the assist laser, is used to irradiate a Ti s

We developed two methods for depositing hydroxyapatite (HAp) coatings based on the pulsed laser ablation, laser irradiation and laser-assisted laser ablation (LALA) techniques. In laser irradiation, the HAp coatings were deposited in air. LALA involv
