We study theoretically a nonresonant optical creation of a one-dimensional exciton-polariton condensate in a semiconductor microcavity. The polariton condensate is treated in the mean-field approach, taking into consideration an antitrapping potential created by the reservoir of noncondensed particles. Polariton condensates are excited by multiple lasers, with a combination of continuous wave and pulsed sources. The proposed pump-probe configuration leads to the realisation of various experimental schemes, e.g. optical trapping of a polariton condensate in real space. Moreover, it can be utilised for investigation of elementary excitations in the time domain when polariton condensates from two sources interact with each other.
