摘要

从科学的角度来看，高功率、脉冲太赫兹辐射和高磁场的结合是非常有前途的。我们提出了一种在高场苦磁体内的太赫兹单色泵浦探针装置的设计，该装置使用的元件不在常规准光学太赫兹装置的范围内。我们使用特殊的波导和棱镜将泵和探针光束在空间上分开，这使我们能够在小孔径磁铁的低温环境中工作。我们的测试结果表明，该泵浦探针插入可以利用回旋共振研究半导体中的快速载流子动力学。

THz Pump-Probe Setup for Experiments in High Magnetic Fields

The combination of high power, pulsed THz radiation and high magnetic fields is very promising from a scientific perspective. We present the design of a THz single-color pump-probe setup inside a high-field Bitter magnet, using components that are not within the scope of regular quasi-optical THz setups. We use special waveguides and prisms to spatially separate the pump and the probe beams, which allow us to work in a cryogenic environment in a small bore magnet. Our test results show that this pump-probe insert enables studying the fast carrier dynamics in semiconductors using cyclotron resonance.
