Efficient THz generation via stimulated Raman adiabatic passage

论证了在三能级系统中经由受激拉曼绝热过程产生太赫兹,分析了基本模型和泵浦激光与太赫兹产生相干的三能级的理论,并应用在横向激励二氧化碳激光光学泵浦重水分子中,可以产生波长为385μm的太赫兹辐射.产生的太赫兹脉冲功率表现为蒸汽压的函数,并得到了最高太赫兹功率.该技术提供了一种鲁棒性非常好的产生太赫兹的方法.

A THz generation via stimulated Raman adiabatic passage in three-level A system was demonstrated. The basic model and theory had been analyzed in three levels coherent with pump laser and THz generation. The application also had been mentioned in D20 molecules optically pumped by a TEA CO2 laser. It produced THz radiation at the wavelength of 385 μm. The power of the THz pulse as a function of the vapor pressure, and a maximum THz power had been obtained. It was displayed that this technology is a robustness method of THz source.
