A compact Yb atomic beam apparatus. mm, mm, mm.
Temperature dependence of the electrically-heated rare-earth dispenser oven depending on the supplied current I at two different positions of exit hole (open circle) and reservoir body (open square). A differential heating effect is clearly seen.
(a) Resonance fluorescence spectra of the 1 S 0↔ 1 P 1 transition for different Yb isotopes at 398.9 nm as functions of frequency detuning Δ1 at 398.9 nm for I = 32 A (upper trace) and 24 A (lower trace). F’s are total angular momentum quantum numbers for odd isotopes. (b) Spectroscopically-measured atomic beam flux (open circle) of the 174Yb isotope at the center of the source chamber as well as the oven temperature (open square) depending on the supplied current I. Solid lines in (b) are results of best fits.
(a) Resonance fluorescence spectra near the resonant two-photon excitation (Δ1 = 0) at three different wavelengths as a function of Δ2. Inset shows the relevant energy level diagram of Yb atoms. (b) Resonance fluorescence intensities at two-photon resonance excitation (Δ1 = Δ2 = 0 and P 1 = 7.5 mW) as a function of P 2.
