title: [Mollow profile with seven peaks under double coupling fields].
abstract: Transparency and absorption overlaping with Mollow profile in a lambda three-level scheme driven by two coupling fields was investigated. There are two degenerate hyperfine levels within ground state. A strong coupling field and a probing field interact with the same optical transition between the excited state level and the first ground state hyperfine level, and an additional weak coupling field interacts with the excited state level and the second ground state hyperfine level, which is named double coupling lambda three-level scheme. It can be seen that when the strong coupling field is off-resonant, there is the superposition of Mollow profile with EIT, EIA and other quantum coherent phenomena, namely, Mollow profile with seven peaks. The dependence of the position of the EIT or EIA on Rabi frequency and frequency detuning of the strong coupling field was investigated. The results can be accounted for by dressed-state formalism.
