通过改变飞秒脉冲激励脉冲的脉宽和啁啾方向，可以控制磁场中InAs的THz辐射光谱。较长的激发脉冲宽度产生较低频率的THz辐射。此外，正啁啾脉冲激发将产生更高功率和更高频率的太赫兹辐射。(C)1999年美国物理学会。[S0003-6951（99）02530-9]。
The THz radiation spectrum from InAs in a magnetic field irradiated with femtosecond pulses can be controlled by varying the excitation pulse width and chirp direction of the excitation pulse. A longer excitation pulse width produces lower-frequency THz radiation. Also, positively chirped pulse excitation will generate higher power and higher frequency THz radiation.
