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 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.

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

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 Ceramic Laser Reflectors are high reflectance cavities used in solid state and CO2 laser systems. They are built either as a one-piece or two-piece system based on customer requirement.Ceramic cavities produce diffuse reflectance, which offers a very uniform beam profile. This diffuse reflectance also distributes light and consequently decreases hot spots in the pumped medium. These completely dense materials (e.g. Al2O3) exhibit higher strength and scratch resistance than traditional polymeric and thermoplastic materials.

Nd:YVO4 is the most efficient laser crystal for diode-pumped solid-state lasers. The good physical, optical and mechanical properties make Nd:YVO4 an excellent material for high power, stable and cost-effective diode-pumped solid-state lasers.

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.

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:YAG (Neodimium Doped Yttrium Aluminum Garnet) has been and continue to be the most widely used laser crystal for solid-state lasers.

Ceramic Laser Reflector (Ceramic Laser Cavity) works particularly well in Ruby, Nd:YAG, or Alexendrite laser pumping chambers and can be a highly cost effective alternative to metal coated reflectors. Compared to metal reflectors, ceramic units offer higher reflectivity and therefore enhanced laser power. Surfaces can be sealed and coated with a solarization-resistant glaze to give high bulk reflectivity.

When choosing a window, the user should consider whether the material's transmission properties and the mechanical properties of the substrate are consistent with specific requirements of the application. Coating is another important issue for choosing a proper window. WISOPTIC offer a wide variety optical windows with different coatings, e.g. anti-reflection coated precision windows for Nd:YAG laser applications.

Nd:YVO4 (Neodymium-doped Yttrium Vanadate) is the most efficient laser crystal for diode-pumped solid-state lasers. Its good physical, optical and mechanical properties make Nd:YVO4 an excellent crystal for high power, stable and cost-effective diode-pumped solid-state lasers, especially for lasers with low or middle power density. Nd:YVO4  is a good choice for highly polarized output at 1342 nm, as the emission line is much stronger than those of its alternatives.

Diffusion Bonded Crystal (DBC) is a crystalline solid used in photo optic applications. It 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.

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.

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

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.

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.

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.

Ytterbium Doped Yttrium Aluminum Garnet (Yb:YAG) is more suitable for diode-pumping than the traditional Nd-doped laser crystal. Compared with the commonly used Nd:YAG, Yb:YAG has the following advantages: three to four times lower thermal loading per unit pump power and much larger absorption bandwidth to reduce thermal management requirements for diode lasers, longer upper-laser level lifetime.

Basically all Pockels cell drivers are made based on solid-state electronic technology, using high voltage transistors such as MOSFETs. Multiple high voltage transistors may have to be stacked, taking care to achieve an even distribution of voltage across those. Instead of using some heavily isolated floating gate drive circuitry for the different transistors, one may use certain advanced ideas such as implementing so-called avalanche switch stacks involving avalanche diodes and/or avalanche bipolar transistors.Device lifetimes can be very long, provided that properly engineered
