    China Manufacturer for Caf2 - Tm:YAP Crystals – Dien

    Tm doped crystals embrace several attractive features that nominate them as the material of choice for solid-state laser sources with emission wavelength tunable around 2um. It was demonstrated that Tm:YAG laser can be tuned from 1.91 up to 2.15um. Similarly,Tm:YAP laser can tuning range from 1.85 to 2.03 um.The quasi-three level system of Tm:doped crystals requires appropriate pumping geometry and good heat extraction from the active media.On the other hand,Tm doped materials benefit from a ...

    Chinese wholesale Q Switch - Achromatic Depolarizers – Dien

    These achromatic depolarizers consist of two crystal quartz wedges, one of which is twice as thick as the other, that are separated by a thin metal ring. The assembly is held together by epoxy that has been applied only to the outside edge (i.e., the clear aperture is free from epoxy), which results in an optic with a high damage threshold. These depolarizers are available uncoated for use in the 190 – 2500 nm range or with one of three antireflection coatings deposited on all four surf...

    New Fashion Design for Ho,Cr,Tm:Yag - 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...
