我们提出了一种新的基于强抽运和探测脉冲的时域光谱技术。强抽运强探测(SPSP)技术提供了不受抽运和探测脉冲持续时间限制的时间分辨率。通过对多能级振动模型的SPSP信号进行精确的数值模拟，我们发现SPSP信号在时间尺度上表现出明显短于脉冲持续时间的电子和振动拍频。这表明SPSP光谱学有可能应用于实时研究分子过程，这些过程不能用微弱的泵浦和探测脉冲的泵浦-探测光谱学在时间上分辨。
We propose a new time-domain spectroscopic technique that is based on strong pump and probe pulses. The strong-pump strong-probe (SPSP) technique provides temporal resolution that is not limited by the durations of the pump and probe pulses. By numerically exact simulations of SPSP signals for a multilevel vibronic model, we show that the SPSP signals exhibit electronic and vibrational beatings on time scales which are significantly shorter than the pulse durations. This suggests the possible application of SPSP spectroscopy for the real-time investigation of molecular processes that cannot be temporally resolved by pump-probe spectroscopy with weak pump and probe pulses.
