研究目的
Investigating the THz generation efficiency from MIR two-color laser pulse induced gas plasma and the control of the relative phase between the pulses.
研究成果
The peak intensity decreases more significantly with the central wavelength than the generation efficiency increases. A simple method to control the relative phase of the MIR two-color pulse was found, which is further capable to compensate the temporal walk-off between the pulses.
研究不足
The study is theoretical, and practical implementation may face challenges not addressed in the simulations.
