We examine the conical terahertz emission from the superluminous ionization front created in air by an axicon-focused femtosecond laser pulse. We develop the theoretical model that explains the experimental results and predicts new possibilities to control terahertz pulse parameters.
我们研究了飞秒激光脉冲通过轴棱锥聚焦在空气中产生的超亮电离前沿的圆锥形太赫兹发射。我们提出了一个理论模型,解释了实验结果,并预测了控制太赫兹脉冲参数的新可能性。
