    摘要: A method of producing a marking on a diamond. For producing the marking, the region on the surface of the diamond which is to be marked is irradiated with an argon fluorine excimer laser whose output beam is passed through a mask which defines the marking. The diamond selectively absorbs the excimer laser radiation and undergoes a partial allotropic transformation without losing its diamond crystal lattice configuration.
