Electromagnetically induced transparency and dark fluorescence in a cascade three-level diatomic lithium system

Following our previous brief report Phys. Rev. Lett. 88, 173003 2002 , we report here a detailed study of electromagnetically induced transparency EIT and dark fluorescence in a cascade three-level diatomic lithium system using optical-optical double resonance OODR spectroscopy for both resonance and off resonance coupling. When a strong coupling laser… CONTINUE READING
