从理论上论证了一种利用频率比为1:3(800 nm+267 nm)和1倍:4(1600 nm+267 nm)的反向旋转双圆场有效地产生高椭圆度阿秒脉冲的方案。结果表明,可以产生椭圆度为0.54(800°+267 nm)和0.79°(1600°+400 nm)的有效阿秒脉冲。我们还研究了高次谐波产额的标度律。结果表明,在频率比较高的双圆场中,高次谐波的强度可以增加一个数量级以上。通过对驱动场的对称性和经典电子轨迹的分析,解释了高次谐波的高椭圆度和高效率。
We theoretically demonstrate a scheme to efficiently generate attosecond pulses with high ellipticity by a counter-rotating bicircular field with frequency ratio of 1 : 3 (800 + 267 nm) and 1 : 4 (1600 + 400 nm). It is shown that efficient attosecond pulses with high ellipticity of 0.54 (800 + 267 nm) and 0.79 (1600 + 400nm) can be generated. We also investigate the scaling law of high harmonic generation yield. It is shown that the intensity of the high harmonics can be increased by more than one order of magnitude in the bicircular fields with higher frequency ratios. The high ellipticity and high efficiency of high harmonics are explained by analyzing the symmetry of driving field and the classical electron trajectories.
