It was recently predicted [Phys. Rev. A95(6), 063817 (2017) 10.1103/PhysRevA.95.063817] that an intense femtosecond laser pulse propagating in an electro-optic crystal and producing free carriers via multiphoton ionization can generate a unipolar electromagnetic precursor propagating ahead of the laser pulse. Here we report the experimental observation of this phenomenon in a GaP crystal excited by an amplified Ti:sapphire laser.
最近有预测 [《物理评论A》95(6)，063817 (2017) 10.1103/PhysRevA.95.063817] 表明，在电光晶体中传播并通过多光子电离产生自由载流子的强飞秒激光脉冲能够产生一个在激光脉冲之前传播的单极电磁前驱波。在此，我们报告在由放大的钛宝石激光激发的GaP晶体中对这一现象的实验观察结果。
