Terahertz Time-Domain Spectroscopy System THZ-TDS-S

Frequency Range: 0.1-4THz Dynamic Range: >=55dB Frequency Resolution: <=10GHz

This terahertz time-domain spectroscopy system uses a femtosecond laser to drive a THz emitter and electro-optic sampling for coherent electric-field detection. Simultaneous amplitude/phase acquisition enables calculation of refractive index, absorption coefficient, dielectric constant and conductivity. Standard, broadband and imaging versions offer configurable transmission, reflection, 2D scanning, temperature control, cryogenic and optical-pump/THz-probe accessories. Open optics and modular software support upgrades/development. The laser splits into pump/probe beams; the pump drives a nonlinear crystal to generate THz pulses, which interact with the sample and enter an electro-optic detection crystal. An adjustable delay changes probe/THz timing. Balanced detection records polarization changes to reconstruct the time-domain field. Fourier transforms and modeling of sample/reference signals yield complex optical parameters.
