The effects of nitrogen and oxygen background gases to the properties of femtosecond pulsed laser deposited Nd:YAG thin film are investigated. Our results show differences in the reflectivity and FTIR spectra of the thin films. These differences may be attributed to the nucleation behavior as dictated by the free energy per unit volume. The experiment showed that background gas can be used to control and improve properties of the femtosecond pulsed laser deposited Nd:YAG film.
