Collective spontaneous emission from a one-dimensional mesoscopic exciton system interacting via static dipole moments is investigated by virtue of the analogy to the quantum XXZ spin chain. The rigorous expression for the initial state is obtained at any degree of excitation from the ground state by a short intense laser pulse. The emission profile from the initial state with partial population inversion exhibits oscillations and very rapid decay in comparison with that from the completely inverted state. The time-resolved emission spectra are also discussed.
