It is shown that highly localized solitons can be created in lower dimensional Bose-Einstein condensates (BEC), trapped in a regular harmonic trap, by temporally varying the trap frequency. A BEC trapped in such a trap can be effectively used to construct a pulsed atomic laser emitting coherent atomic wave packets. It is also shown that one has complete control over the spatio-temporal dynamics of the solitons. The dynamics of these solitons are compared with those constructed in a BEC where the trap frequency is constant.
