摘要

我们展示了一种基于光泵浦-太赫兹探针光谱的空间分辨方法来测量载流子寿命和载流子分布。泵浦-探头延时范围为600 ~ 200 μs。空间分辨率优于50 μm(中心/6,1THz)。

Time-domain optical pump — Terahertz probe spectroscopic imager for carrier lifetime measurements in the pico- to microsecond regime

We demonstrate a spatially resolved method to measure carrier lifetimes and carrier distributions based on optical pump - terahertz probe spectroscopy. The pump-probe delay range spans from 600 ps to 200 μs. The spatial resolution is sub-wavelength being better than 50 μm (<; λ<;sub>center<;/sub>/6 at 1THz).
