    Factory made hot-sale Nd Yag Crystal - 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:...

    The YAG (yttrium aluminium garnet) laser can be doped with chromium and neodymium in order to enhance the absorption characteristics of the laser. The NdCrYAG laser is a solid state laser. Chromium ion (Cr3+) has a broad absorption band; it absorbs the energy and transfers it to the neodymium ions (Nd3+) by way of dipole-dipole interactions. Wavelength of 1.064 µm is emitted by this laser. The laser action of Nd-YAG laser was first demonstrated at the Bell Laboratories in the year 1964. The N...

    Glan Laser prism polarizer is made of two same birefringent material prisms that are assembled with an air space. The polarizer is a modification of the Glan Taylor type and is designed to have less reflection loss at the prism junction. The polarizer with two escape windows allow the rejected beam to escape out of the polarizer, which makes it more desirable for high energy lasers. The surface quality of these faces is relatively poor as compared to that of entrance and exit faces. No scratc...

    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 ...

    AGS is transparent from 0.50 to 13.2 µm. Although its nonlinear optical coefficient is the lowest among the mentioned infrared crystals, high short wavelength transparency edging at 550 nm is made use of in OPOs pumped by Nd:YAG laser; in numerous difference frequency mixing experiments with diode, Ti:Sapphire, Nd:YAG and IR dye lasers covering 3–12 µm range; in direct infrared countermeasure systems, and for SHG of CO2 laser. Thin AgGaS2 (AGS) crystal plates are popular for ultrashort pulse ...
