我们演示了使用光脉冲整形技术结合差频产生在一个非线性的光电晶体产生合成波形在太赫兹频率。使用Gerchberg-Saxton算法编程并在空间光傅立叶滤波器中准备的光谱相位调制产生定制的太赫兹脉冲，包括啁啾脉冲，零面积脉冲和多脉冲序列，用于高达2.0 THz的可调谐窄带太赫兹辐射。(C)2003年美国光学学会。
We demonstrate the use of optical pulse-shaping technique in conjunction with difference frequency generation in a non-linear optoelectronic crystal for generating synthesized waveforms at terahertz frequencies. Spectral phase modulations, programmed using Gerchberg-Saxton algorithm and prepared in a spatial light Fourier filter, produce tailored terahertz pulses, including chirped pulses, zero-area pulses, and trains of multiple pulses for tunable narrow-band terahertz radiation up to 2.0 THz.
