通过使用飞秒激光的差频产生演示了正向和反向传播太赫兹世代。通过冷却晶体以减少太赫兹损耗，我们实现了1.36和0.65太赫兹的太赫兹世代。温度相关的测量结果表明，随着温度从2553k降低到143k，太赫兹脉冲强度逐渐增加，中心频率发生红移，但光谱带宽没有显著降低。
Forward and counterpropagated backward terahertz generations were demonstrated via difference frequency generation using a femtosecond laser. By cooling the crystal to reduce terahertz losses, we achieved the terahertz generations of 1.36 and 0.65THz. Temperature-dependent measurements showed gradual intensity increase of the terahertz pulse and red shift of the center frequency as the temperature decrease from 255to143K, although there were insignificant decreases of the spectral bandwidth.
