Ladder-Lambda和Double-Lambda系统中相干太赫兹脉冲的产生
Generation of strong short coherent terahertz pulses in Ladder-Lambda and Double-Lambda systems
摘要：
我们表明，相干驱动的原子或分子介质可能产生强可控的太赫兹辐射短脉冲。该方法是基于最大的量子相干性在气体介质中的光脉冲和相干散射的红外辐射产生脉冲的太赫兹辐射的激发。在室温下，脉冲的能量范围从几nJ到$μ$ J，持续时间从几fs到ns。
英文摘要：
We show that coherently driven atomic or molecular media potentially yield strong controllable short pulses of THz radiation. The method is based on excitation of maximal quantum coherence in a gas medium by optical pulses and coherent scattering of infra-red radiation to produce pulses of THz radiation. The pulses have the energies range from several nJ to $μ$J and time durations from several fs to ns at room temperature.
