Abstract The photoassociation reactions H+D+ and H++D induced by the one- and two-colour laser pulses are theoretically studied. The reactions occur through two channels: (i) H(1S)+D+ →HD+, and (ii) H++D(1S)→HD+. The reaction probability through channel (ii) is higher than through channel (i). The populations of the products H++D and HD+ and the ratio of H++D to HD+
can be controlled by laser pulses. The two-colour laser pulses can more
efficiently lower the dissociation probability and therefore enhance the
yield ratio of the product HD+.
