Abstract

We experimentally demonstrate the double dark resonance windows characteristic of a four level tripod system such as the D₂ line of ⁸⁷Rb where the F_g = 1, m_g = -1, 0, 1 Zeeman sublevels form the bottom three levels and the F_e = 0 state is the upper level. Between the double dark resonance windows, a very narrow absorption resonance is observed whose line-width is shown to be sub-Doppler and sub-natural. The sharp absorptive resonance is characterized as a function of applied magnetic field and pump laser power.
