摘要：Cavity linewidth narrowing via double-dark resonances is experimentally observed using the Rb-87 Zeeman splitting sublevels. With the steep dispersion led by the interacting dark resonances in the tripod-type electromagnetically induced transparency system, we narrow the cavity linewidth to 250 kHz at room temperature. Furthermore, the position of this ultranarrow cavity linewidth can be tuned in a 60 MHz coupling field detuning range. (C) 2013 Optical Society of America
