Two-photon optical frequency reference with active ac Stark shift cancellation

Abstract

An optical reference based on a two-photon optical transition with ac Stark shift cancellation is proposed. The reference uses two interrogating laser fields at different frequencies. Compared to conventional optical two-photon references, the new approach offers the possibility for improved short-term stability resulting from a higher signal-to-noise and improved long-term stability due to active ac Stark shift cancellation. We demonstrate the ac Stark shift cancellation method on the $5s{{}^{2}S}_{1/2}\to 5d{{}^{2}D}_{5/2}$ two-photon transition in ${}^{87}$Rb.
