RD-20479RADIATION-HARD OPTICAL ARTICLES FROMSINGLE-CRYSTAL DIAMOND OF HIGH ISOTOPICAbstractSingle-crystal diamond consisting of isotopicallyenriched carbon-12 has been found to have a very high degreeof radiation hardness, typically greater by a factor of morethan 10 than that of natural type IIa diamond. Therefore, itis possible to fabricate optical articles therefrom, such aslaser windows, lenses, gratings and mirrors and activematerials for lasers.
