The photoassociation reaction H+D+ induced by two chirped pulses is theoretically studied. The first pulse is employed to accelerate the collision pairs, and the second pulse is used to enhance the yield ratio of HD+. The optimal parameters of the second pulse and the population of product HD+ depend on the chirp rate of the first pulse. The population of the product HD+ can be controlled by the delay time between the two laser pulses.
