Anotace	A thorough study on sp3 to sp2 carbon conversion in undoped and boron-doped diamond (BDD) thin ( 500 nm) layers leading to the desired sp2/sp3 carbon ratio and lateral distribution, which utilizes boron atom incorporation and infrared (IR) material laser processing has been performed. Polycrystalline as-grown (AG) or chem-mechanically polished (CMP) undoped diamond/BDD layers were investigated with respect to boron content and laser wavelength (800, 1030 nm). Boron incorporation leads to an increase in IR optical absorption and reduction of required energy fluence ( th 1 J cm−2) needed for sp3 to sp2 carbon conversion. Raman spectroscopy was performed to identify carbon conversion stages and to tailor the ideal parameters for other IR laser sources and required sp2/sp3 carbon ratio. Electrochemical parameters ( p and Ap/ Cp ratio) were obtained from cyclic voltammetry measurements of outer-([Ru(NH3)6]3＋/2＋) and inner-([Fe(CN)6]3−/4−) sphere redox markers.
