Pulsed laser deposition (PLD) is widely used to prepare various kinds of thin films. From many experimental results the film surface has been found to be strongly affected by so-called droplets, which are relatively large target material particles in solid or liquid state carried with the plume. In order to satisfy both purposes of high deposition rate and good quality by the PLD, we have investigated the plume reflection process from the viewpoint to avoid the big particles deposited on the substrate. In the present paper we investigate the influences of the system parameters on surface thin film quality and the deposition rate. Some optimization proposals are also included for this deposition technique.
