    Factory wholesale 2940nm Laser Crystal - KTP Crystal – Dien

    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. The frequency-doubling properties of GaSe were studied in the wavelength range between 6.0 µm and 12.0 µm. GaSe has been successfully used for efficient SHG of CO2 laser (up to 9% conversion); for SHG of pulsed CO, CO2 and chemical DF-laser (l = 2.36 µm) radiation; upconversion of CO...

    Factory directly Neodymium Yag - Rochon Polarizer – Dien

    Rochon Prisms split an arbitrarily polarized input beam into two orthogonally polarized output beams. The ordinary ray remains on the same optical axis as the input beam, while the extraordinary ray deviates by an angle, which depends on the wavelength of the light and the material of the prism (see the Beam Deviation graphs in the table to the right). The output beams have a high polarization extinction ratio of >10 000:1 for the MgF2 prism and >100 000:1 for the a-BBO prism. Feature:...

    China wholesale Zngep2 Crystals - BaGa2GeSe6 Crystals – Dien

    The BaGa2GeSe6 crystal has a high optical damage threshold (110 MW/cm2), a wide spectral transparency range (from 0.5 to 18 μm) and a high nonlinearity (d11 = 66 ± 15 pm/V) , which makes this crystal very attractive for frequency conversion of laser radiation into (or within) the mid-IR range. It was proved probably the most efficient crystal for second harmonic generation ofCO- and CO2-laser radiation. It was found that a broadband two-stage frequency conversion of multi-lineCO-laser radiati...

    Reasonable price Near Infrared Crystal - Er,Cr:Glass/Er,Cr,Yb:Glass – Dien

    Erbium and ytterbium co-doped phosphate glass has a broad application because of the excellent properties. Mostly, it is the best glass material for 1.54μm laser due to its eye safe wavelength of 1540 nm and high transmission through atmosphere. It’s also suitable for medical applications where the need for eye protection may be difficult to manage or diminish or hinder essential visual observation. Recently it is used in optical fiber communication instead of EDFA for its more super pl...
