Broadband Terahertz Emission Module BTEM-B
The broadband THz emitter module is optimized for high-frequency generation using ultrathin ZnTe or BNA. Crystal thickness, pump duration, spot and phase matching are optimized to reduce absorption/propagation mismatch limiting high frequencies. Wider usable coverage combines with electro-optic sampling, dry paths and fast delay scanning for molecular vibrations, lattice dynamics, ultrafast semiconductors and broadband-device tests. Ultrashort pumping creates transient second-order polarization; thinner crystals reduce absorption/velocity mismatch, retaining higher-frequency output. Pump energy, focus and thickness balance bandwidth and intensity.
