  The realisation of optically detected magnetic resonance via nitrogen vacancy
centers in diamond faces challenges at high magnetic fields which include
growing energy consumption of control pulses as well as decreasing
sensitivities. Here we address these challenges with the design of shaped
pulses in microwave control sequences that achieve orders magnitude reductions
in energy consumption and concomitant increases in sensitivity when compared to
standard top-hat microwave pulses. The method proposed here is general and can
be applied to any quantum sensor subjected to pulsed control sequences.
