A new modality for probing ultrafast phenomena that relies on radially or azimuthally polarized probe pulses is presented. First, we describe the principle and then theoretically analyze the signals expected for different types of pump-induced nonlinearities. Last, we experimentally verify the methodology by probing a pump-induced Kerr gate with a time-delayed radially polarized probe pulse. In general, we find excellent agreement between the simulated and measured results.
提出了一种用于探测超快现象的新方法,该方法依赖于径向或方位角偏振探测脉冲。首先,我们描述原理,然后从理论上分析不同类型泵浦诱导非线性所预期的信号。最后,我们通过用延迟的径向偏振探测脉冲探测泵浦诱导的克尔门来实验验证该方法。总体而言,我们发现模拟结果与测量结果之间具有很好的一致性。
