利用两束同色圆偏振激光场产生水窗区间阿秒脉冲
Generation of the water window attosecond pulses by using single-color two circularly polarized pulses
摘要
Abstract
We theoretically investigated the generation of the high -order harmonic and the isolated attosecond pulse when a model He atom was exposed to the single -color two circularly polarized pulses .The results showed that by properly choosing the wavelength , the carrier envelope phase ( CEP) and the delay time of the two laser pulses , not only the harmonic cutoff energy is remarkably enhanced , but also the harmonic yield is enhanced , resulting in a supercontinuum with the bandwidth of 500 eV.Finally, by superposing a properly selected harmon-ics in the supercontinuum region , a series of sub-35 as pulses in the water window region can be obtained .关键词
