Outline of Final Research Achievements

In this research, we have developed and applied an optical parametric chirped-pulse amplifier, which is capable of delivering 0.55 mJ, 10 fs infrared pulses with a repetition rate of 1 kHz at 1600 nm to generate high harmonics in the water window. The spectra of soft x-ray radiation exhibit the clear dependence on the electric waveform of the sub-two-cycle infrared pulses. The cutoff of soft x-ray harmonics reaches 325 eV, which is well beyond the carbon K edge. The waveform dependence indicates the generation of isolated attosecond soft x-ray pulses. Furthermore, we have upgrade the parametric amplifier and the millijoule infrared pulses from the upgraded light source generate bright soft x-ray radiation at the carbon K edge. This yield enhancement is necessary for the characterization of the attosecond soft x-ray pulses based on time-resolved photoelectron spectroscopy and the demonstration ultrafast soft x-ray absorption spectroscopy, which we are working on.
