Description
Atomic clocks already play a crucial role in the modern world: most famously forming the backbone of the global positioning system. Those atomic clocks operate at microwave frequencies, but newer atomic clocks operating at optical frequencies can offer substantially greater precision.
A great deal of work has been done in recent years towards the miniaturisation of optical atomic clocks, which has consisted mainly of shrinking a number of key components, such as the frequency comb, lasers and electronics. Another key component is the atomic vapour cell, with new microfabricated vapour cells potentially offering smaller size and lower cost compared to traditional glassblown cells. We present our recent work utilising these microfabricated vapour cells, detailing clock performance results where our existing rubidium two-colour optical clock is fitted with one such cell. Measurements of clock frequency stability and other parameters are discussed and compared with existing cell designs.
