| Research Abstract |
We have developed a novel broadband infrared laser pulse source, the wavelength of which spans form 1.2μm to 2.1 μm. This laser source can potentially generate an isolated attosecond pulse with the high-order harmonic generation to observe and control quantum states in atoms and molecules, even though the laser system should be improved. The preliminary study by using an existing harmonic beam line with a 12-fs Ti:sapphaire laser revealed the sub-20 fs dynamics of the nuclear wave-packet (WP) generated on the adiabatic potential of D_<2+>/H_<2+> molecule. This was the first observation the WP pumped with a sub-10 fs extreme ultraviolet pulse and probed with a vacuum ultraviolet pulse.
