研究了非线性啁啾激光脉冲对拍频光混频产生窄带太赫兹脉冲的光谱线宽和强度。给出了泵浦脉冲展宽器的色散与太赫兹脉冲啁啾之间的直接关系。得到了太赫兹谱线宽度和强度的简单解析表达式，并通过数值模拟证实了其有效性。实现了具有最小啁啾的窄带太赫兹脉冲的产生。
The spectral linewidth and intensity of narrowband terahertz pulses generated by photomixing with beating of nonlinearly chirped laser pulse pairs are studied. The direct relationship between the dispersion of the pump pulse stretcher and the chirp of the terahertz pulse is shown. Simple analytical expressions for the linewidth and intensity of the terahertz spectrum are obtained and their validity is confirmed by numerical simulations. Generation of narrowband terahertz pulses with minimal chirp is demonstrated.
