    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.

  • 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.

  • GaSe Crystal

    GaSe Crystal

    Gallium Selenide (GaSe) non-linear optical single crystal, combining a large non-linear coefficient, a high damage threshold and a wide transparency range. It is a is very suitable material for SHG in the mid-IR.

  • ZnTe Crystal

    ZnTe Crystal

    Zinc Telluride is a binary chemical compound with the formula ZnTe. DIEN TECH fabricates ZnTe crystal with crystal axis <110>, which is an ideal material applied to guarantee a pulse of terahertz frequency through a nonlinear optical process called optical rectification using high-intensity light pulse of subpicosecond. The ZnTe elements DIEN TECH provides are free from twin defects.
