Diamond thin films were grown on diamond (100) substrates in oxygen atmospheres by pulsed laser deposition (PLD) using an ArF excimer laser. The optimum oxygen atmosphere of 5 × 10-2 Torr can etch the sp2 bonding fractions preferentially. At substrate temperatures between 550°C and 600°C, single-phase diamond films consisting of diamond crystal with diameters of 1-5 μm could be grown. The results demonstrated that the diamond thin films can be homo-grown using PLD by the optimization of the deposition parameters such as the oxygen pressure and the substrate temperature.
