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).

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.

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

LiNbO3 (Lithium Niobate, LN) crystal is a multifunctional material that integrates properties of piezoelectric, ferroelectric, pyroelectric, nonlinear, electro-optical, photoelastic, etc. LiNbO3 has good thermal stability and chemical stability.Among the EO crystals, LN and DKDP are the two primary material that have been practical. DKDP crystals can be easily grown with a high optical homogeneity, which can satisfy the requirement of a large caliber Pockels cell.

    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.

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.

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.

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.

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.

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.

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.

E-O Q-switch based on DKDP (KD*P) crystals are one of the most popular Pockels cells in the market.Deuterated potassium dihydrogen phosphate has good transmission from 390 nm to 1400 nm (0.39 μm – 1.4 μm) and combined with high electro-optical coefficients makes it suitable for Pockels cells.Highly deuterated DKDP (D>99% – WISOPTIC) is necessary to reach effective electro-optical response.

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.
