AbstractA systematic study of the composition of metal films thermally deposited by laser heating (cw 514 nm) of the group VI hexacarbonyls is described. The films are found to contain significantly lower levels of carbon and oxygen than photochemically deposited films, and are spatially inhomogeneous. Estimates of temperature to determine the extent of laser heating permit the kinetics of this process to be compared to ∞ desorption from single crystal surfaces.

ABSTRACTThe physical processes occurring during the initial stages of ultrafast laser heating of metals are described. Femtosecond laser irradiation is used to create nonequilibrium heating in metals. In such a nonequilibrium state, the electron temperature can be heated up to a few thousand degrees above the lattice temperature. Electron-lattice relaxation is time-resolved in copper and found to be 1 – 4 ps depending on the laser heating ffuence. The technique of time-resolved electron diffraction (a lattice structural and temperature probe) is described. Utilization of this technique for lattice temperature measurement of thin metal films is demonstrated.
