    Optical contacted Crystal

    In order to provide a broad-band phase matching in THz generation and detection and keep the frequency resolution high enough at the same time,DIEN TECH successfully developed refractive combined  ZnTe/GaP crystal- a 10µm thickness (110) ZnTe/GaP crystal on a (100)ZnTe/GaP substract. In such crystals the THz-optical co-propagation is only crucial within the<110> part of the crystal, and the multiple reflections have to span the full combined crystal thickness.

  • MgO:LN crystal

    MgO:LN crystal

    MgO-Doped Lithium Niobate (MgO:LN) Crystals is the most dominant nonlinear crystalline material for terahertz (THz) coherent radiation in both commercial instrumentation and fundamental research.Compatible with nanosecond, picosecond and femtosecond pump regimes, covering all mainstream THz source types: continuous-wave, narrowband tunable pulses and ultrabroadband high-field transients.

  • PPLN crystals

    PPLN crystals

    Periodically Poled Lithium Niobate(PPLN crystals) transprant in the range of 0.4–4.5 μm, covering visible, near-infrared and mid-infrared bands up to 3–4.5 μm. It has a very high nonlinear coefficient; the single-pass conversion efficiency of pulsed lasers can reach 80%, several times higher than KTP and LBO. Widly used in tunable OPO light sources, ultrafast spectroscopy, quantum experimental platforms, etc.

  • GaP crystal

    GaP crystal

    Gallium phosphide (GaP) single crystal is a standard material for terahertz (THz) systems.Compared with zinc telluride (ZnTe), GaP features suppressed two-photon absorption and a higher laser damage threshold, making it compatible with high-power Yb-doped fiber femtosecond pump lasers operating at 1030 nm / 1064 nm.

  • Undoped KGW

    Undoped KGW

    Undoped KGW crystal is a high-performance monoclinic double tungstate crystal with outstanding Raman conversion properties and excellent optical stability.

  • Yb:KGW
