An exact treatment of the nonequilibrium dynamics of hard-core bosons (HCB) in one-dimensional (1D) configurations with an underlying lattice was studied. It was shown that quasi-long-range correlations develop dynamically and lead to the formation of quasicondensates of HCB at quasimomenta. The dynamics of the formation of these quasicondensates was also studied. It was found that these systems could be used to create atom lasers since the quasicondensate develops quickly and decays slowly.
