Recent results obtained at the Advanced Laser Light Source (ALLS) are opening new opportunities in further advancing the temporal resolution of Terahertz-field-driven X-ray (TFDX) streak cameras. High-energy, few-cycle mid-infrared (MIR) lasers have been developed, which currently could be found in only a few laboratories in the world. Using the intense MIR and near-IR beam lines at ALLS, ultra-intense THz sources with ~5 MV/cm THz electric field have been developed. This is 10 times that used by Früling et al., and thus could greatly improve the temporal resolution of the TFDX streak camera, down to the few femtosecond level.

先进激光光源 (ALLS) 的最新成果为进一步提高太赫兹场驱动 X 射线 (TFDX) 条纹相机的时间分辨率提供了新的机会。高能、少周期中红外（MIR）激光器已经开发出来，目前世界上只有少数实验室可以使用。利用 ALLS 的强中红外和近红外光束线，已经开发出了具有 ~5 MV/cm 太赫兹电场的超强太赫兹源。这是 Früling 等人使用的方法的 10 倍，因此可以极大地提高 TFDX 条纹相机的时间分辨率，低至几个飞秒级别。
