Abstract

We present a tunable, frequency-stabilized, narrow-bandwidth source of frequency-degenerate, entangled photon pairs. The source is based on spontaneous parametric downconversion in periodically poled KTiOPO4. Its wavelength can be stabilized to 850 or 854nm, thus allowing to address two transitions in Ca+40 ions. Its output bandwidth of 22MHz coincides with the absorption bandwidth of the calcium ions. Its spectral power density is 1.0 generated pairs/(s MHz mW).

Scheme of the experimental setup. The master laser is stabilized to an atomic line (transfer lock), amplified, and frequency doubled (laser source). The doubled light is downconverted in a type-II phase-matched PPKTP crystal (SPDC source). The photon pairs are split and fiber coupled; one of the photons is spectrally filtered (spectral filtering). The time correlator detects the coincident pairs. Later, the unfiltered photon will be sent to a single ion experiment. Symbols are explained in the text.
