Controlling Amplitude and Radiation Pattern of Emitted Terahertz by Group Velocity Mismatch

In this paper, the effect of group velocity mismatch on the characteristic of terahertz (THz) radiation from a plasma irradiated by two-color laser pulses is investigated. The group velocity mismatch is directly related to the slippage-limited interaction length (SLIL). In order to control the chara...
