Development of the read-out system for the quantum mechanical amplitude and phase information using the frequency and time resolved spectroscopy

在低温固体对氢晶体中成功地制备了波包干涉实验装置。利用自制的迈克尔逊干涉仪制备了相位稳定的600nm和800nm双脉冲激光。创建的波包的动态被另一个fs探测脉冲探测。频率分辨信号由CCD检测器检测。我们观察到信号条纹对比度的寿命非常长，甚至在初始波包准备500ps后仍超过60%。

I have succeeded to prepare the experimental setup for the wave packet interferometry experiment within the low temperature solid para-hydrogen crystal. The phase-stabilized double pulses of 600nm and 800nm fs laser pulses were prepared by a home-built Michelson interferometer. The dynamics of the created wave packets were probed by another fs probe pulse. The frequency resolved signal was detected by a CCD detector. We observed an extraordinary long lifetime of the signal fringe contrast, more than 60% even after 500ps from the initial wave packet preparation.
