- Abstract: We study the superradiant emission of an inverted spin ensemble strongly
coupled to a superconducting cavity. After fast inversion, we detune the spins
from the cavity and store the inversion for tens of milliseconds, during which
the remaining transverse spin components disappear. Switching back on resonance
enables us to study the onset of superradiance. A weak trigger pulse of a few
hundred photons shifts the superradiant burst to earlier times and imprints its
phase onto the emitted radiation. For long hold times, the inversion decreases
below the threshold for spontaneous superradiance. There, the energy stored in
the ensemble can be used to amplify microwave pulses passing through the
cavity.
