| Research Abstract |
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.
