A simplified optical lattice clock

While existing optical lattice clocks demonstrate a high level of performance, they remain complex experimental devices. In order to address a wider range of applications including those requiring transportable devices, it will be necessary to simplify the laser systems and reduce the amount of support hardware. Here we demonstrate two signficant steps towards this goal: demonstration of clock signals from a lattice clock based solely on semiconductor laser technology, and a method for finding the clock transition (based on a coincidence in atomic wavelengths) that removes the need for access to extensive frequency metrology hardware.
