We consider the formation and vibrational stabilization of cold heteronuclear molecules using infrared nanosecond pulses. Starting with a pair of colliding cold atoms of dissimilar species, our objective is the formation of a molecule in its electronic and vibrational ground level by means of the interaction with the laser field. In order to meet this goal, we propose the employment of a single pulse with a time-dependent frequency following a predefined transition pathway. We show that the proposed scheme can efficiently form cold molecules in the vibrational ground level. Calculations are performed for a model representing the formation of LiCs molecules in the milikelvin temperature range. (AU)
