Open-loop wave-packet engineering was demonstrated by full capture of the phase-controlled vibrational motions by means of our newly developed wave-packet spectrometer. Optimal parameters of tailored femtosecond pulses from a pulse shaper were obtained for selective excitation of either twisting or bending motion in two different cyanine dye molecules. Mode-selective wave-packet generation by chirped pulse sequences was found to be commonly effective for DTTCI, DNTTCI and SMP-39. These results suggest a promising step toward triggering chemical reactions to a desired target by guiding the wave-packet motions associated with conformational changes in the substances.

利用我们新研制的波包谱仪，通过完全捕获相控振动运动，证明了开环波包工程。利用脉冲整形器获得了选择性激发两种不同花菁染料分子弯曲或扭曲运动的飞秒脉冲的最佳参数。通过啁啾脉冲序列的模式选择性波包生成被发现对于DTTCI、DNTICI和SMP-39是普遍有效的。这些结果表明，通过引导与物质构象变化相关的波包运动，向触发化学反应到所需目标迈出了有希望的一步。
