Cube PBS-manufacture,factory,supplier from China

WISOPTIC offers both plate and cube PBS for a variety of wavelength ranges and power handling requirements.

A corner cube (or cube corner), also known as a retroreflector, is an optical component with the unique ability to return an incoming beam of light directly towards its point of origin regardless of the beam's angle of entry. This property makes this prism type ideal for a wide variety of applications, such as laser resonator cavities, land surveying, ground based range-finding, satellite communications and space vehicle docking.Wisoptic offer a wide variety of retroreflectors at competitive prices and lead times, and are able to accommodate the most demanding requirements.

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.

Corner cube prisms are optics which act as corner reflectors. The basic operation principle is that there are internal reflections on three mutually orthogonal prism surfaces, producing a direction of a reflected beam which is nominally parallel to the direction of the incident beam – with the accuracy limited only by the accuracy of the surface orientation of the prism. Precision prisms can offer excellent parallelism of incoming and reflecting beams. It is usually specified as an angular deviation, e.g.

Polarizing Beamsplitters (PBS) splits incident unpolarized light into two perpendicular linearly polarized light. Among them, p-polarized light passes through completely, while s-polarized light is reflected at 45 deg which makes the emitting direction of s-light vertical to p-light. Additionally, beamsplitters can be used in reverse to combine two different beams into a single one. Beamsplitters are often classified according to their construction:cube or plate.Cube PBS are fabricated using two typically right angle prisms.

Optical beamsplitters play a vital role in many laser-based measurement and positioning systems. Although the operation of a typical beamsplitter is conceptually simple, its performance characteristics can dramatically affect the accuracy and repeatability of the overall system. Consequently, understanding the variables that distinguish beamsplitter performance is an important step in comparing and specifying components.

Pure LiNbO3 (LN) is a good candidate for various optical devices, but has a major disadvantage due to its low threshold optical damage. MgO:LN (congruent compositions) is one of the possible solutions to deal with this problem. MgO doping has played an important role in LN and shown an increased threshold laser beam strength by 100 times. An interesting point is that every physical property of MgO:LN (e.g.

Bandpass Filters are used in a variety of industries, including machine vision,factory automation, security and surveillance, license plate recognition, medical and life science, agricultural inspection, aerial imaging, motion analysis, photography and cinematography.WISOPTIC's bandpass filters include mass collection of  dielectric-coated filters, colored glass filters, neutral density filters, spatial filters, and tunable optical filter based on liquid crystal technology. Specifically speaking, e.g.

    Potassium dideuterium phosphate DKDP (KD * P) crystal has low optical loss, high extinction ratio, and excellent electro-optical performance. DKDP Pockels cells are made by using the longitudinal effect of DKDP crystals. The modulation effect is stable and the pulse width is small.

Characterized by the excelent UV transmission, high damage threshold, and high birefringence, KDP (Potassium Dihydrogen Phosphate)  and KD*P (Potassium Dideuterium Phosphate) are useful commercial NLO materials for doubling, tripling and quadrupling of Nd:YAG laser at room temperature or an elevated temperature. They are also excellent electro-optic (EO) crystals with high electro-optic coefficients, widely used as electro-optical modulators and Pockels cells for Q-switched lasers.

Polymer-matrix Gain Medium for Pulsed Dye Laser (PDL)Polymer matrix can be used to make solid laser gain medium of dye lasers.  Compared with the commonly used liquid-state dye laser unit, the solid-state material has many advantages, such as the convenience of handling, the various options of dimensions and shapes. But the dye molecules in the polymer matrix might degradate in a limited time by triplet excitation, or even destruct permanently. To avoid this shortage, WISOPTIC provides long quality guarantee period of every piece of Dye Laser Cell/Rod made in-house.

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.

Potassium Dihydrogen Phosphate (KDP) and Potassium Dideuterium Phosphate (KD*P, DKDP) crystals are among the most widley used nonlinear crystals. Both of these crystals are routinely used for the doubling, triplingand quadrupling of Nd:YAG lasers at room temperatures.

RTP possesses a large electro-optic impact for light propagating along either the x or y direction (electric powered along z). It functions right optical transparency from around 400nm to over 4µm. RTP offers a high resistance to optical damage with energy ~1Gw/cm2 for 1ns pulses at 1064nm. It is largely total lack of piezo-electric resonances at 200kHz and probable beyond. The primary distinction between RTP and BBO whilst used for Q-switching pertains to the common power degree at which the Q-switch is capable of be used practically.

RTP (Rubidium Titanyl Phosphate - RbTiOPO4) is a very desirable crystal material for E-O modulators and Q-switches. It has advantages of higher damage threshold (about 1.8 times that of KTP), high resistivity, high repetition rate, no hygroscopic or piezoelectric effect. As biaxial crystals, RTP’s natural birefringence needs to be compensated by use of two crystal rods specially oriented so that beam passes along the X-direction or Y-direction.

A Pockels cell driver is a high-voltage regulated power supply, either pulse or continuous, allowing to control a birefringence of an electro-optical crystal (KTP, KD*P, BBO, etc.) in order to drive the polarization direction of the light propagating through the crystal.WISOPTIC has developed and produces a variety of Pockels cell drivers for different applications: from very simple compact devices for q-switching to precise and powerful fast models for pulse picking, cavity damping, regenerative amplifier control, etc.

BBO（Beta-Barium Borate, β-BaB2O4）based Pockels cells operate from approximately 0.2 - 1.65 µm and are not subject to tracking degradation. BBO exhibits low piezoelectric response, good thermal stability, and low absorption. Low piezoelectric ringing makes this Pockels cell attractive for the control of high-power and high-pulse repetition rate (hundreds of kilohertz, up to 1MHz) lasers.

LBO (LiB3O5) is an excellent non-linear crystal of Borate-family following BBO. LBO has advantages of good ultraviolet transmittance (210-2300 nm), high laser damage threshold and large effective frequency doubling coefficient (about 3 times of KDP crystal). Therefore LBO is commonly used to produce high power second and third harmonic laser light, especially for ultraviolet lasers.LBO has large band gap and transparency region, high non-linear coupling, good chemical and mechanical properties.

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.

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.

Optical windows are made in the form of flat plates of a transparent medium that allow light into an instrument. Windows have high optical transmission with little distortion of the transmitted signal, but can not change the magnification of the system.

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.
