In modern THz time-domain spectroscopy (THz-TDS), the common approach is THz pulses generation by optical rectification (OR)of ultrashort laser pulses and then the detection by free space electro-optic sampling (FEOS) in nonlinear crystals of special orientation. In optical rectification, the ban...
GaSe crystals Using a GaSe crystal the output wavelength was tuned in the range of from 58.2 µm to 3540 µm (from 172 cm-1 to 2.82 cm-1) with the peak power reaching 209 W. Significantly improved was made to the output power of this THz source from 209 W to 389 W. ZnG...
New BGGSe crystals High optical damage threshold (110 MW/cm2) Wide spectral transparency range (from 0.5 to 18 μm) High nonlinearity (d11 = 66 ± 15 pm/V) Typically applied in frequency conversion of laser radiation into (or within) the mid-IR range Most efficient crystal for second harmonic...
