| 摘 要： | 系统地研究了任意偏振双色相干场高次谐波，结果表明单个圆偏振光不能产生高次谐波，在适当的条件下，某些谐波可以部分或完全消失，而某些谐波可以得到加强，产生更高次谐波高转换效率的条件是双色线偏振场的结合。

High Order Harmonic Generation of Two Colour Coherent Laser Fields with Arbitrary Polarization |
| |
| Abstract: | The high order harmonic generation by two-colour coherent laser fields of arbitrary polarization (1ω plus 2ω or 3ω) is studied systematically. The results show that a single circularly polarized field can not emit high harmonics, under some conditions some order harmonics can be enhanced and some can be eliminated or decreased. The high order harmonic generation has a strong dependence on the ellipticity of the fundamental field and the mixing of different fields. |
