We investigate cooperative emission from a rubidium vapor, and demonstrate a controlled transition from yoked superfluorescence to three-photon-induced superradiance by driving the medium with co-propagating ultrashort laser pulses. We study temporal emission profiles and time delays on a picosecond time scale and compare the measured pulse shapes with simulations. Our results suggest strategies to improve efficiency of mirrorless lasers and superradiant light sources.
