Nitrogen-vacancy centers in diamond are studied extensively over the past decades. Their properties as quantum system feature a wide range of applicability. A new approach is the growth of high nitrogen doped CVD-diamond to create ensembles of nitrogen-vacancy centers for the purpose of measuring sensitive magnetic fields by laser threshold magnetometry. The challenge arises from keeping detrimental material effects low such as absorption and the incorporation of other magnetic moments. Within this study we investigate the nitrogen incorporation in CVD-diamond depending on nitrogen flow and growth rates. A comparison of growth series with different crystallographic oriented substrates shows new insight in the varying dependencies.
