  • Abstract
    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).
