Thin film polarizers are based on interference within a dielectric optical thin-film coating on a thin glass substrate. They are made from composed materials which include a polarizing film, an inner protective film, a pressure-sensitive adhesive layer, and an outer protective film. Thin film polarizers are used for polarization separation, that's to say to change un-polarized beam into linear polarized beam.

A prism, in optics, is a piece of glass or other transparent object surrounded by two planes that intersect but are not parallel to each other. The most important parameters of a prism are the angle and material.  Prisms are capable to redirect light at a designated angle or adjust the orientation of an image. Therefore prism is useful for in certain spectroscopes, instruments for analyzing light and for determining the identity and structure of materials that emit or absorb light. An optical prism’s design determines how light interacts with it.

LiNbO3 crystal is a low cost photoelectric material with good mechanical and physical properties as well as high optical homogeneity. It has been widely used as frequency doublers for wavelength > 1mm and optical parametric oscillators (OPOs) pumped at 1064nm as well as quasi-phase-matched (QPM) devices. With preferable E-O coefficients, LiNbO3 crystal has become the most commonly used material for Q-switches and phase modulators, waveguide substrate, and surface acoustic wave (SAW) wafers, etc.

Solid Laser DyesThere is some work on dye lasers based on solid media, e.g.

Also we offer uncoated rectangular windows with aperture from 15 x 20 to 50.8 x 50.8 mm and thickness from 2 to 10 mm.

Barium Borate exists in three major crystalline forms: alpha, beta, and gamma. The low-temperature beta phase converts into the alpha phase upon heating to 925 °C. β-BBO differs from α-BBO by the positions of the barium ions within the crystal. Both phases are birefringent, however α-BBO has centric symmetry and thus does not has the same nonlinear properties as β-BBO.α-BBO is a negative uniaxial crystal with a large birefringence over the broad transparent range from 189 nm to 3500 nm.

Diffusion bonded crystal consists of two, three or more parts of crystals with different dopants or same dopant with different doping levels. This material is commonly made by bonding one laser crystal with one or two undoped crystals by precise optical contact and further processing under high temperature.

RTP (RbTiOPO4) is an isomorph of KTP crystal. RTP single crystals are grown in WISOPTIC by a slow-cooling flux method. RTP has many advantages e.g. large nonlinear optical coefficient, large E-O coefficient, high damage threshold (about 1.8 times of KTP), high resistivity, high repetition rate, no hygroscopy and no induced piezo-electric effect with electrical signals up to 60 kHz.

Pockels Cell Driver for Q-Switching of Flashlamp Pumped LasersThese drivers are designed for Q-switching of nanosecond flashlamp pumped lasers without use of phase retardation plates, for example to drive a DKDP Pockels cell in YAG lasers for aesthetic therapy. High voltage is applied to Pockels cell in order to inhibit oscillation.

The periodic polarized KTP (PPKTP) is a novel nonlinear optical material that can be customized to achieve all of the nonlinear applications required in the entire KTP crystal transmission band, without the phase matching limitations of conventional KTP. Moreover, the effective nonlinear coefficient of PPKTP is about 3 times higher than that of conventional KTP. In the nonlinear application of conventional KTP, the crystal must have a single domain structure, but PPKTP crystal has an artificially induced periodic domain structure.

Nd:YAG (Neodymium Doped Yttrium Aluminum Garnet, Nd:Y3Al5O12) has been and continues to be the most mature and most  widely used crystals for lasers, no matter solid state or lamp pumped, CW or pulsed. It possesses a combination of properties uniquely  favorable for laser operations. Nd:YAG crystals are used in all types of solid-state lasers systems-frequency-doubled continuous wave, high-energy Q-switched, and so on.

Nd:YVO4 (Neodymium-doped Yttrium Vanadate) is one of the best commercially available material for diode-pumped solid-state lasers, especially for lasers with low or middle power density. For example, Nd:YVO4 is a better choice than Nd:YAG for generating low-power beams in hand-held pointers or other compact lasers. In these applications, Nd:YOV4 has some advantages over Nd:YAG, e.g.

Yb:YAG is more suitable for high power diode-pumped lasers than the traditional Nd-doped systems.

One of the most important drawbacks of popular LiNbO3 crystal is its susceptibility to photorefractive damage (optically induced change of refractive index, usually under exposure with blue or green CW light). The usual way to eliminate this effect is to keep LN crystals at elevated temperatures (400K or more). Another way to prevent photorefractive damage is MgO-doping (usually at levels of around 5 mol% for congruent LN).
