Abstract
Pump-probe spectra of caesium D2 line are experimentally investigated in a Cs atomic vapour cell with co-propagating orthogonal linearly-polarized pump and probe laser beams. Absorption-reduction dips duo to electromagnetically induced transparency (EIT) in multi-Λ-type Zeeman sublevels of 6 S1/2 F=3-6 P3/2 F′=2 hyperfine transition and absorption-enhanced peaks due to electromagnetically induced absorption (EIA) in 6 S1/2 F=4-6 P3/2 F′=5 hyperfine transition are demonstrated. With detuned pump beam abnormal sign-reversed signals inside the EIT dip and the EIA peak are clearly observed.
