Investigation of Nonequilibrium Dynamics of Nickel Film Excitated by Femtosecond Laser

Abstract:

Using femtosecond laser pump-probe technique, the transient change in nickel film reflectivity after excitation by femtosecond laser pulse was measured, which indicated the thermalization process of the nickel film. A novel mechanism of the themalization process of the nickel film was proposed to interpret experimental results. It is found that the trend of the transient reflectivity change and the temperature change of nickel film excitated by femtosecond laser pulse are attributed to the special energy gap of the nickel film.
