Dye Handpieces 585nm-manufacture,factory,supplier from China

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.

WISOPTIC use in-house made dye laser cells to make dye laser handpieces. Pure input beam at 532nm is required to produce output beams of 585nm/595nm (energy over 100 mJ) and 650nm/660nm (energy over 80 mJ).

Dye laser headpiece made from WISOPTIC has very high conversion efficiency: 65%~75% for 532/585nm, 45%~55% for 532/650nm.

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.

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

Cr: YAG is an excellent crystal for passive Q-switching diode pumped or lamp-pumped Nd:YAG, Nd:YLF, Nd:YVO4 and other Nd or Yb doped lasers at wavelength from 800 nm to 1200 nm. With advantages of chemical stability, durable, UV resistant, good thermal conductivity and high damage threshold (＞500 MW/cm2 ) and being easy to be operated, Cr:YAG is used widely to substitute for many traditional materials such as LiF, organic Dye and color centers.

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.

LBO (LiB3O5) is a kind of non-linear optical crystal with good ultraviolet transmittance (210-2300 nm), high laser damage threshold and large effective frequency doubling coefficient (about 3 times of KDP crystal). So 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.

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.

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.

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.

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.

Polarization is an important characteristic of light. Polarizers are key optical elements for controlling your polarization, transmitting a desired polarization state while reflecting, absorbing or deviating the rest. There is a wide variety of polarizer designs, each with its own advantages and disadvantages.

Optical filter is usually a component with a wavelength-dependent transmittance or reflectance. It's used to selectively transmit or reject a wavelength or range of wavelengths.  Filters with particularly weak wavelength dependence of the transmittance are called neutral density filters. The general applications of optical filters include fluorescence microscopy, spectroscopy, clinical chemistry, machine vision inspection, etc. Bandpass interference filters are designed to transmit a portion of the spectrum, while rejecting all other wavelengths.

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.

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.

A right angle prism is an optical prism designed to deviate light by 90° or 180°, depending on the orientation of the prism and the face through which light enters. The joining edges and faces are perpendicular to the base faces, and all joining faces are rectangular. They are often  preferable to plane mirrors, because they are easier to mount and align.

KTP (KTiOPO4) is one of the most commonly used nonlinear optical materials. For example, it’s regularly used for frequency doubling of Nd:YAG lasers and other Nd-doped lasers, particularly at low or medium-power density. KTP is also widely used as OPO, EOM, optical wave-guide material, and in directional couplers.KTP exhibits a high optical quality, broad transparency range, wide acceptance angle, small walk-off angle, and type I and II non-critical phase-matching (NCPM) in a wide wavelength range.

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. Due to the low piezoelectric coupling coefficients of BBO, BBO Pockels cells function at repetition rates of hundreds of kilohertz.

Beta-BBO crystal is an important nonlinear optical crystal with combination of unique optical properties, such as broad transmission and phase matching ranges, large nonlinear coefficient, high damage threshold and excellent optical homogeneity. The β-BBO crystal is an efficient material for the second, third and fourth harmonic generation of Nd:YAG lasers, and the best NLO material for the fifth harmonic generation at 213 nm.

High temperature phase of α-BBO Crystal (BaB2O4) is one of the excellent birefringent crystals. It is characterized by large birefringent coefficient and wide transmission window ranged from 189nm to 3500nm. Due to its high chemical stability and medium hardness, α-BBO is fabricated easily into many kinds of optical components.The physical, chemical, thermal and optical properties of α-BBO are similar to those of β-BBO.

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.

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.
