Abstract:
A thin film deposition apparatus, comprising:means for providing at least one laser pulse having a pulse duration of 100 picoseconds or less a source of deposition material within an evacuated chamber; means for directing said at least one laser pulse onto said source of deposition material to produce a plasma; a substrate; means for positioning said substrate to be in the path of said plasma, wherein said plasma is deposited on said substrate; means for delivering said at least one laser pulse as predominately S-polarized light onto said source of deposition material when a growth rate lower than that achieved when using predominately P-polarized or predominately circularly polarized light is desired; and means for delivering said at least one laser pulse as predominately P-polarized or predominately circularly polarized light onto said source of deposition material when a growth rate higher than that achieved when using predominately S-polarized light is desired.
