    Wholesale Ags - Nd:YAP Crystals – Dien

    Nd:YAP  AlO3 perovskite (YAP) is a well known host for solid state lasers. The crystal anisotropy of YAP offers numerous advantages.It permits a small tuning of wavelength by varyingthe wave vector direction in the crystal. Furthermore, the output beam is linearly polarised. Advantages of Nd:YAP Crystals: Comparable threshold and slope efficiency at 1079nm to Nd:YAG at 1064nm Higher efficiency at 1340nm compared to Nd:YAG at 1319nm Linearly polarized output beam Higher absorption in water and...

    Rapid Delivery for Optical Interference Filter - Achromatic Waveplates – Dien

    Achromatic waveplates by using two pieces of plates.It is similar to Zero-order waveplate except that the two plates are made from different materials,such as crystal quartz and magnesium fluoride. Since the dispersion of the birefringence can be different for the two materials,it is possible to specify the retardation values at a wavelength range. Features: Spectrally Flat Retardance Operating Ranges from UV to Beyond Telecom Wavelengths AR Coatings for: 260 – 410 nm, 400 – 800 nm, 690...

    China Factory for Xenon Lamp - 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...

    Good quality Far Infrared Crystal - 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...
