THz Generation ZnTe crystals 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 sampl...
ZnSe Fresnel rhombs Fresnel rhombs are excellent achromatic retarders with Low Temperature Sensitivity and Broader Wavelength Range than Waveplate,it changes retardance with wavelength arises only from the change in refractive index.Like broadband waveplates pro...
Terahertz sources have always been one of the most important technologies in the field of THz radition.Lots of ways had been proved functional to achieve THz radition.Typically, telectronics and photonics techologies. In the filed of photonics, nonlinear optical differen...
CSOE 2022 The development of science and the achievements of major scientific and technological increasingly depend on the cross and integration of different disciplines. Photonics technology, as t...
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 ...
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 effic...
