We report on progress in the development of subsystem-level devices which serve as building blocks for the next generation of portable atomic clocks. Specifically, we discuss the engineering of small, low-power, low-temperature strontium vapour dispensers and a compact optical resonator useful for the stabilisation of multiple lasers.
