Abstract
© 2016 Optical Society of America.We observe an inverted crossover resonance in f-driven four-level systems, where F' - F = 0; + 1. The signal is observed through saturated absorption spectroscopy of the (6s2 )1 S0-(6s6p) 3 P1 transition in 171Yb, where the nuclear spin I = 1?2. The enhanced absorption signal is used to generate a dispersive curve for 556 nm laser frequency stabilization and the stabilized light cools 171Yb 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 inter-combination line in ytterbium.
