摘要：

The photoionization of D-2 and dissociation of the resultant D-2(+) are monitored by pump-probe measurements using intense near-infrared few-cycle laser pulses. The yields of D-2(+) and D+ recorded up to the pump-probe delay time of 527 ps exhibit oscillatory structures reflecting the motion of the created vibrational wave packet of D-2(+), and the Fourier transform of the data in time domain reveals the vibrational level separations with uncertainties of 0.0002-0.0097 cm(-1), showing a potential application of the strongfield pump-probe measurements to high-resolution spectroscopy of molecular ions.
