We observe an inverted crossover resonance in π-driven four-level systems, where F − F = 0, +1. The signal is observed through saturated absorption spectroscopy of the (6s 2 ) 1 S 0 − (6s6p) 3 P 1 transition in 171 Yb, where the nuclear spin I = 1/2. The enhanced absorption signal is used to generate a dispersive curve for 556 nm laser frequency stabilisation and the stabilised light cools 171 Yb atoms in a two-stage magneto-optical trap, achieving temperatures of 20 µK. The Doppler-free spectroscopy scheme is further used to measure isotopic frequency shifts and hyperfine separations for the intercombination line in ytterbium.

We carry out investigations of inverted crossover resonances in π-driven four-level systems where ∆F can be zero. Through the use of sub-Doppler frequency modulation spectroscopy of the (6s 2 ) 1 S 0 − (6s6p) 3 P 1 transition in 171 Yb the resonance becomes manifest. The centre-frequency is inherently insensitive to first-order Zeeman shifts and equates to the two-level resonance frequency in the absence of a magnetic field. A rate equation model is used to help validate the nature of the resonance. Optical frequency measurements of the F ′ = 1/2 hyperfine line recorded over two months demonstrate a statistical uncertainty of 2 × 10 −11 . The inverted crossover resonance found with the F ′ = 3/2 line is used for 556 nm laser frequency stabilization, which is an alternative means when applied to magneto-optical trapping of 171 Yb.PACS numbers: 42.62.Eh; 42.62.Fi; 32.30.Jc; 37.10.De; 32.10.Fn ‡ To distinguish the two 171 Yb 1 S 0 − 3 P 1 hyperfine lines we will only state the upper F value for the sake of simplicity.

“…The precision of wavelength meter was 10 −4 nm, which (for the wavelength of 174 Yb inter-combination transition under investigation) corresponds to 100 MHz in the frequency scale. Isotopic shifts for natural ytterbium were measured in [41]. The neighboring isotopic lines for 174 Yb are 176 Yb and 172 Yb, which are shifted by −954 MHz and +1 GHz, correspondingly.…”

Collision-induced photon echo at the transition0↔1in ytterbium vapor: Direct proof of depolarizing collision anisotropy

et al. 2011

A collision-induced photon echo arising at the transition 0 ↔ 1 of ytterbium in the presence of heavy atomic buffer is investigated. Collision-induced echo signal appears in the case of mutually orthogonal linear polarizations of exciting pulses and it is absent without buffer. Collision-induced echo power grows with buffer pressure up to the maximum value and decays exponentially at further buffer pressure growth. Collision-induced echo power is essentially less than that of the ordinary echo generated by pulses with parallel polarizations in the same mixture, and its polarization is linear with the polarization vector directed along that of the first exciting pulse. All the properties of collision-induced photon echo are explained on the basis of collision relaxation dependence on the direction of active atom velocity.
