ABSTRACT:
A method of depositing diamond-like films produces depositing species from a plasma of a hydrocarbon gas precurser. The plasma is generated by a laser pulse which is fired into the gas and is absorbed in an initiater mixed with the gas. The resulting detonation produces a plasma of ions, radicals, molecular fragments and electrons which is propelled by the detonation pressure wave to a substrate and deposited thereon.
