In order to realise these broad applications it will be necessary to build miniaturised, portable diamond masers that can be readily integrated into existing standards but demonstrations of diamond masers to date have required the bulky electromagnets of Electron Paramagnetic Resonance (EPR) spectrometers to provide a sufficiently homogeneous magnetic field. Here we discuss different strategies for relaxing the homogeneity requirement for the magnetic field by optimising the diamond and characterise the performance of diamond masers employing customised gain media in which the concentrations of 13C nuclei and nitrogen-vacancy spins are varied. We conclude by discussing recent progress in the development of miniaturised diamond masers.
