Abstract Generation of intense broadband terahertz (THz) waves from gas plasma induced by tri-color ultrashort (fundamental (ω), second harmonic (2ω), and third harmonic (3ω)) laser pulses is theoretically investigated. Simulation results show that the 3ω laser pulse can greatly enhance or suppress the generation of THz wave at different values of relative phase (θ3) between the 3ω and ω fields. Moreover, the polarities of the generated THz waves can be controlled by changing θ3, with the relative phase θ2 (between the 2ω and ω fields) fixed to be a certain value. All of our results show that θ3 plays a key role in the generation process, which promises to control the intensity as well as the polarity of gas plasma-induced THz radiation.

Online attention
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.
