AB - <p style="text-align: justify;">Laser induced dissociation control of the symmetric diatomic molecular ion $H_2^+$ and the triatomic
molecular ion $H_3^{2+}$&nbsp;is discussed. The simulation results demonstrate that a long-wavelength terahertz or mid-infrared
laser pulse can be used to control the electrons of the dissociative states after the excitation of an
ultrashort ultraviolet (UV) laser pulse. For $H_2^+,$ there exists an effective time, which increases with increasing
pulse duration of the UV laser pulse, for controlling the molecular dissociation. For the electrons of the $1sσ_g$
 state, they move along the polarization direction of the dissociation control electric field. In contrast, for the
electrons of the $2pσ_u$ state, they move in the opposite direction to that of the electric force. And for the
triatomic molecule $H_3^{2+}$, the electron dissociation control can also be realized by changing the central
wavelength of the exciting UV pulse.</p>
