  • KTA Crystal

    KTA Crystal

    Potassium Titanyle Arsenate (KTiOAsO4), or KTA crystal, is an excellent nonlinear optical crystal for Optical Parametric Oscillation (OPO) application. It has better non-linear optical and electro-optical coefficients, significantly reduced absorption in the 2.0-5.0 µm region, broad angular and temperature bandwidth, low dielectric constants.

  • KTP Crystal

    KTP Crystal

    Potassium Titanyl Phosphate (KTiOPO4 or KTP) KTP is the most commonly used material for frequency doubling of Nd:YAG and other Nd-doped lasers, particularly when the power density is at a low or medium level. To date, extra and intra-cavity frequency doubled Nd:lasers using KTP have become a preferred pumping source for visible dye lasers and tunable Ti:Sapphire lasers as well as their amplifiers. They are also useful green sources for many research and industry applications.

  • 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.

  • PPKTP Cystals

    PPKTP Cystals

    Periodically poled potassium titanyl phosphate (PPKTP) is a ferroelectric nonlinear crystal with a unique structure that facilitates efficient frequency conversion through quasi-phase-matching (QPM).
  • HgGa2S4 Crystal

    HgGa2S4 Crystal

    High values of laser damage threshold and conversion efficiency allow to use Mercury Thiogallate HgGa2S4 (HGS) non-linear crystals for frequency doubling and OPO/OPA in the wavelength range from 1.0 to 10 µm. It was established that SHG efficiency of CO2 laser radiation for 4 mm length HgGa2S4 element is about 10 % (pulse duration 30 ns, radiation power density 60 MW/cm2). The high conversion efficiency and wide range of radiation wavelength tuning allows to expect that this material may compete with AgGaS2, AgGaSe2, ZnGeP2 and GaSe crystals in spite of the considerable difficulty of big size crystals growth process.
