|
| 理论研究了谐波发射的量子路径在非均匀正交激光场下的调控机制。结果表明，在适当的双色激光偏振角和非均匀参数的组合下，不仅谐波截止能量有明显增大；谐波发射的短量子路径可以被单独选择出来对谐波连续区起到贡献作用。并且，该方案在长脉宽激光下依然适用。最后，利用谐波连续区可以获得脉宽在50 as的孤立阿秒脉冲。 |

|
| The control of the quantum path of harmonic emission driven by the orthogonal laser has been theoretically investigated. The results show that, under the proper combination of the polarization angle of the two-color pulse and the inhomogeneous parameter, not only the harmonic cutoff can be obviously increased, but also the short quantum path can be selected to contribute to the harmonic continuum. Moreover, the present scheme is still suitable for longer duration lasers. Finally, by using the harmonics on the harmonic continuum, the isolated attosecond pulses of 50 as can be obtained. |
