    "abstract": "We observe pulse delays of up to twenty times the input pulse duration when\n200-ps laser pulses pass through a hot Rb 85 vapor cell. The pulse peak travels\nwith a velocity equal to c/20, and the energy transmission is 5%. For pulses\nwith linewidth greater than typical features in the atomic dispersion, pulse\ndelay is predicted and observed for all center frequencies near resonance.\nPulse advance is never observed. The measurements are in good agreement with a\nthree-level linear-dispersion calculation. We are able to control the amount of\ndelay by using a steady-state laser beam for optical pumping of the ground\nstates prior to sending in the test pulse.",
