  Next-gen­er­a­tion light sources ne­ces­si­tate the use of x-ray op­ti­cal com­po­nents ca­pa­ble of han­dling high power den­si­ties. Di­a­mond, with its ex­cep­tional ther­mal and me­chan­i­cal prop­er­ties, is an ideal ma­te­r­ial for re­frac­tive fo­cus­ing op­tics. Pol­ished di­a­mond x-ray lenses ex­hibit min­i­mal back­ground scat­ter­ing. Over the past sev­eral years, we have been en­gaged in the de­vel­op­ment of a pro­duc­tion process for x-ray re­frac­tive di­a­mond lenses. Si­mul­ta­ne­ously, nu­mer­ous other re­search groups have been pur­su­ing vari­a­tions of this task. Re­cently, we have en­tered the com­mer­cial mar­ket, of­fer­ing di­a­mond lenses for sale. Some geome­tries have un­der­gone ex­ten­sive test­ing, such as at the ESRF [1], demon­strat­ing fo­cus­ing per­for­mance com­pa­ra­ble to in­dus­try-stan­dard beryl­lium lenses. How­ever, due to the com­plex­ity of the pro­duc­tion process, cer­tain geome­tries are still un­der­go­ing fab­ri­ca­tion de­vel­op­ment and beam­line test­ing. Our process uti­lizes high-pre­ci­sion fem­tosec­ond laser ab­la­tion in com­bi­na­tion with the chem­i­cal me­chan­i­cal pol­ish­ing. This poster re­views our cur­rent progress, out­line the pa­ra­me­ter space for laser ab­la­tion and pol­ish­ing of 1D and 2D lenses.
