We propose and demonstrate a robust generation method of intense isolated attosecond pulses (IAP), which enable us to perform a nonlinear attosecond optics experiment. Our generation scheme is based on the two-color infrared laser field synthesis and the energy-scaling method of HHG. By using our robust generation method, the maximum pulse energy of the IAP reaches as high as 1.3 uJ. The generated pulse with a duration of 500 as, as characterized by a nonlinear autocorrelation measurement, is the shortest and highest-energy pulse ever with the ability to induce nonlinear phenomena. The peak power of our tabletop light source reaches 2.6GW, which even surpasses that of an extreme-ultraviolet free-electron laser.

我们提出并展示了一种强大的孤立脉冲脉冲（IAP）的强大生成方法，这使我们能够执行非线性的AttoSecond Optics实验。我们的一代方案基于两色红外激光场的合成和HHG的能量尺度方法。通过使用我们强大的生成方法，IAP的最大脉冲能达到高达1.3 UJ。以非线性自相关测量为特征的持续时间为500的生成脉冲是有史以来最短和最高的脉冲，具有诱导非线性现象的能力。我们的桌面光源的峰值功率达到2.6GW，甚至超过了极端释放的自由电子激光器的峰值功率。
