Abstract: Hydroxyapatite (HA) have been used as coatings on implants for orthopedics,neurosurgery and dentistry owing to their biocompatible properties. Recently,pulsed laser deposition (PLD) was investigated to produce HA films of high crystallinity and bonding strength. The purpose of this paper is to summarize the present situation of HA films deposited by pulsed laser and systematically review the effect of various parameters of the PLD process on the properties of films,including target properties,ambient gas,substrate temperature,buffer layer,laser wavelength and energy density. Mechanical properties and bioactivity were analyzed,and the application foreground was also prospected.
