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 + .

The laser-induced vibrational state-selectivity of product HF in photoassociation reaction H+F→HF is theoretically investigated by using the time-dependent quantum wave packet method. The population transfer process from the continuum state down to the bound vibrational states can be controlled by the driving laser. The effects of laser pulse parameters and the initial momentum of the two collision atoms on the vibrational population of the product HF are discussed in detail. Photodissociation accompanied with the photoassociation process is also described.
