Ultrafast laser control of backward superfluorescence towards standoff sensing Academic Article

abstract

• We study infrared backward cooperative emission in a rubidium vapor induced by ultrafast two-photon optical excitations. The laser coherent control of the backward emission is demonstrated by using a pair of 100 fs pulses with a variable time delay. The temporal variation (quantum beat) of the backward beam intensity due to interference of atomic transitions in the rubidium atomic level system 5S-5P-5D is produced and controlled. Based on the obtained experimental results, we discuss possible applications of the developed approach for creation of an effective "guide star" in the sodium atomic layer in the upper atmosphere (mesosphere). 2014 AIP Publishing LLC.
