Abstract We studied the high-order harmonic generation of two linearly-polarized orthogonal fields.The results showed that the frequency of the harmonics can be controlled by controlling the relative frequency of the two incident fields,especially, when the frequency of one field is an integral mutiple of the frequency difference between the two incident fields,the fractional times of harmonic can be obtained.

Altmetric calculates a score based on the online attention an article receives. Each coloured thread in the circle represents a different type of online attention. The number in the centre is the Altmetric score. Social media and mainstream news media are the main sources that calculate the score. Reference managers such as Mendeley are also tracked but do not contribute to the score. Older articles often score higher because they have had more time to get noticed. To account for this, Altmetric has included the context data for other articles of a similar age.
