Self-induced transparency and coherent population trapping of 87Rb vapor in a mode-locked laser

Koji Masuda, Christoph Affolderbach, Gaetano Mileti, Jean-Claude Diels & Ladan Arissian

Résumé Simultaneous self-induced transparency and a dark line resonance are observed inside a mode-locked laser. The circulating pulse, tuned to the 795-nm optical resonance of rubidium, has sufficient intensity to create at each passage a population inversion—return to ground state, typical of self-induced transparency. A drop in fluorescence (dark line resonance), is observed as the repetition rate is tuned to a submultiple of the hyperfine ground-state splitting.
