SHG of Nd:Laser - KTP is the most commonly used material for frequency doubling of Nd:YAG and other Nd-doped lasers, particularly when the power density is at a low or medium level.

KTP (KTiOPO4 ) is one of the most commonly used nonlinear optical materials which offers a range of unique features: 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.

Compared to more commonly used KTP crystal, KTA crystal has larger non-linear optical and electro-optical coefficients. KTA has the added benefit of significantly reduced absorption in the 2 to 5 μm region.  It has found more and more applications in second harmonic generation (SHG), sum and difference frequency generation (SFG)/(DFG), optical parametric oscillation/ amplification (OPO/OPA), and electro-optical Q-switching. WISOPTIC do in-house growing and processing KTA crystal with high optical quality and various options of dimensional and coating specifications.

LN crystal has large nonlinear optical coefficient and can easily achieve non-critical phase matching. As an E-O material, LN crystal has been used as an important optical waveguide material.

Gray Track Resistant (GTR) KTP crystals developed by hydrothermal method overcomes the common phenomenon of electrochromism of the flux-grown KTP, thus has many advantages such as high electrical resistivity, low insertion loss, low half-wave voltage, high laser damage threshold, and wide transmission band. So it's very suitable for high power density applications, where regular flux-grown KTP crystals will suffer from gray track damage.GTR-KTP crystal has gray track resistance sufficiently greater than typical flux-grown KTP.

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.

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.

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.

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.

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).

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.

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.

There are four main types of prisms based on the function: dispersion prism, deflection or reflection prism, rotating prism and offset prism.  Deflection, offset and rotating prisms are commonly used in imaging applications; diffusion prisms are designed for dispersive light sources and are not suitable for any application that requires high quality images.WISOPTIC offers a wide range of optical prisms with various designs, substrates, or coatings.

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.

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.

The EO Q-switch (Pockels cell) is an electro-optic device in which the crystal produces linear changes in the birefringence of the crystal (in contrast to the Kerr Effect, which is quadratic with E). Pockels cells are essential components in various optical devices such as Q-switches for lasers, free space electro-optical modulators, free space switches.   WISOPTIC use highly deuterated DKDP (KD*P) crystal (D%>99%) to make high quality Q-switches with high laser induced damage threshold.
