摘要
We experimentally and theoretically demonstrate that ＊~he property （odd or even） of generated harmonics can be selected by manipulating the macroscopic phase-matching conditions based on a three-color laser field. Only odd or even harmonics can be made dominant by changing the focal position and adjusting the gas pressure. These results indicate that the odd-even property of the generated harmonics can be controlled by using the mult i-color laser field with macroscopic phase-matching.
