Abstract

The plasma plume created during the interaction of a KrF laser beam (248 nm) with a graphite target under high-vacuum conditions has been investigated using temporally and spatially resolved spectroscopy and time-of-flight charged particle detection. Measurements lead to information on nature and kinetic energy of ejected particles. Hard carbon films are deposited on various substrates located in front to the target and their properties are investigated. These properties are found close to those of diamond (hardness equals 80 GPa, infrared transparency greater than 90%) when deposition temperature is low (less than 100 degrees Celsius).
