The improved hydrothermal-grown KTP crystal overcomes the common electrochromism damage of flux-grown KTP. The hydrothermal-grown KTP (HGTR-KTP, or GTR-KTP) has high damage threshold, large effective electro-optic coefficients and lower half-wave voltage.  KTP EO Q-switches made by HGTR-KTP crystals utilize thermally compensated double crystal designs. They are mainly used in pulse lasers with narrow pulse width and high repetition frequency.

RTP (Rubidium Titanyl Phosphate - RbTiOPO4) is a robust crystal material suitable for a wide range of E-O applications. It has advantages of higher damage threshold (about 1.8 times that of KTP), high resistivity, high repetition rate, no hygroscopic or piezoelectric effect.

YLF is birefringent, which eliminates thermally induced depolarization loss. The gain and the emission wavelength of Nd:YLF are polarization dependent: there is the stronger 1047nm ray for π polarization, and a weaker one at 1053nm for σ polarization. Nd:YLF provides alternative to the more common Nd:YAG laser crystal for near IR operation.

Alumina Ceramic Reflectors are designed primarily for use in pumping chambers for many diverse laser systems, e.g. YAG lasers.

An aspherical lens features a non-spherical but rotationally symmetric shape with a curvature radius that changes at various points between the center and the edge. Although producing this type of lens is difficult, when manufactured properly, it offers greater functionality than a comparable spherical lens.Spherical Lenses vs. Aspherical LensesSpherical lenses have a spherical surface and the same radius of curvature across the entire lens. In contrast, aspherical lenses have a more complicated surface with a gradually changing curvature from center to edge.

A wave plate, also called a phase retarder, is an optical device that changes the polarization state of light by generating an optical path difference (or phase difference) between two mutually orthogonal polarization components. When the incident light passes through wave plates with different types of parameter, the exit light is different, which may be linearly polarized light, elliptically polarized light, circularly polarized light, etc.

Waveplates (retardation plates or phase shifters) are made from optical materials  with precise thickness such as quartz, calcite or mica, which exhibit birefringence. The velocities of the extraordinary and ordinary rays through the birefringent materials vary inversely with their refractive indices. The difference in velocities gives rise to a phase difference when the two beams recombine.

Yb:YAG's advantage is a wide pump band and an excellent emission cross section. It is ideal for diode pumping. The broad absorption band enables Yb:YAG to maintain uninterrupted pump efficiency across the typical thermal shift of diode output. High efficiency means a relatively small dimension Yb:YAG laser crystal will produce high power output. Based on the YAG host crystal, Yb:YAG can be quickly integrated into the laser design process.

Polarizing Beamsplitters (PBS) are designed to split light by polarization state rather than by wavelength or intensity. PBS are often used in semiconductor or photonics instrumentation to transmit p-polarized light while reflecting s-polarized light. Optical isolators use PBS to eliminate feedback-induced damage. PBS are typically designed for 0° or 45° angle of incidence with a 90° separation of the beams, depending on the configuration.WISOPTIC offers a wide variety of PBS in a range of configurations including plate, cube, or lateral displacement.

Phase retardation plates, or waveplates, are polarizing optics used to manipulate the polarization state of the transmitting light without attenuating, deviating, or displacing the light. The working principle of the plate is to utilize the birefringence of certain materials which separates the incident light beam into two beams along two orthogonal optical axes within the medium. The phase retardation between the two beams of the incident light contributes to changes in the polarization state.

Wisoptic' standard and precision quality laser windows are fabricated from a variety of substrate materials, e.g.  UVFS and N-BK7. They are available either with or without AR coatings, and with dia from 12.5 to 101.6 mm and thickness from 1 to 15 mm. 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.

The most notable benefit of aspheric lenses is their ability to correct for spherical aberration, an optical effect which causes incident light rays to focus at different points when forming an image, creating a blur. Spherical aberration is commonly seen in spherical lenses, such as plano-convex or double-convex lens shapes, but aspheric lenses focus light to a small point, creating comparatively no blur and improving image quality.

LN crystals are nonhygroscopic and have low absorption coefficient and insert loss. In addition, LN crystal can operate stably in a wide temperature range, which makes them the main EO crystal applied in military laser systems.LN electro-optic Q-switches are widely used in Er:YAG, Ho:YAG, Tm:YAG lasers, and are suitable for low-power Q-switched output, especially in laser ranging. LN Pockels cells can be very compact, and the half-wave voltage can be very low. By doping MgO in LiNbO3, the damage threshold of LN Pockels cells can been increased dramatically.

Dye Laser Handpiece are devices that screw onto the end of the laser's arm and convert the energy that the laser produces into different, new wavelengths of light.The two most common dye handpiece wavelengths are 585 nm and 650 nm, which attach to Q-switched Nd:YAG lasers. For these wavelengths to be produced, the Nd:YAG's 1064 nm wavelength is frequency-doubled to produce the 532 nm wavelength, which is then converted by the dye handpieces to produce either 585 nm or 650 nm. WISOPTIC use in-house made dye laser cells to make dye laser handpieces.

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.

RTP crystal is widely used for Electro-Optic applications whenever low switching voltages are required. e.g. in laser Q-switching system with high frequency repetition, high power and narrow pulse width. RTP E-O devices are not only used in laser micromachining and laser ranging, but also in major scientific exploration projects due to their excellent comprehensive performance.As RTP is transparent from 400nm to 3.5µm, it can be used in multiple types of laser such as Er:YAG laser at 2.94µm with fairly good efficiency.

Optical Lenses are designed to focus or diverge light and for imaging or alignment in an optical system. Optical Lenses, which may consist of a single or multiple elements, have a variety of applications. Lens forms can be divided into simple lenses (which include plano-convex lens, plano-concave lens, double-convex lens, double-concave lens, cylinder lens, drum lens, spherical lens in different shapes), achromatic lenses compound lens and multiple types.

Optical lenses can be made in many shapes and may be comprised of a single element or form constituent parts of a multi-element compound lens system. They are used to focus light and images, produce magnification, correct optical aberrations and for projection, mainly controlling the focus or divergence light used in instrumentation, microscopy and laser applications.

Right angle prisms are generally used to bend image paths or redirect light at 90°. This produces a left handed image and depending on the orientation of the prism, the image may be inverted or reverted.

Potassium dihydrogen phosphate KH2PO4 (KDP) is a transparent dielectric material best known for its nonlinear optical and electro-optical properties. Because of its nonlinear optical properties, it has been incorporated into various laser systems for harmonic generation and optoelectrical switching.
