Abstract
We present a compact, cost-effective, and all-digital implementation of a scanning transfer cavity lock (STCL) for long term laser frequency stabilization. An interrupt-based, event-centric state machine is employed to realize the STCL, with the capability to correct for frequency drifts in the slave laser frequency due to changes in lab environmental conditions to within 1.8 MHz for master laser and slave laser wavelengths of 556 nm and 798 nm, respectively. The slave laser is also demonstrated to dynamically scan over a wide frequency range, allowing us to interrogate atomic transitions.Citation
