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.

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.

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.

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.

Optical filters are used to selectively transmit or reject a wavelength or range of wavelengths. Their applications include fluorescence microscopy, spectroscopy, clinical chemistry, machine vision inspection, etc. Optical filters are widely used in light system of life science, imaging, industrial, or defense industries. For example, Bandpass interference filters are designed to transmit a portion of the spectrum, while rejecting all other wavelengths. Notch filters reject a portion of the spectrum, while transmitting all other wavelengths.

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.As one of the most thoroughly characterized nonlinear optical materials, LiNbO3 is suitable for a variety of frequency conversion applications. For example, it is widely used as frequency doublers for wavelength >1 μm and optical parametric oscillators (OPOs) pumped at 1064 nm as well as quasi-phase-matched (QPM) devices.

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.

Tm3+:YLF crystal has a high absorption peak around 792 nm which locates in the diode pumping range, and also has a cross-relaxation process that provides the possibility for each absorbed pump photon to produce to ions at higher laser energy level. Tm3+: YLF laser is very suitable as a pump source for Ho3+:YAG laser. This is due to the good overlap of the emission band of Tm3+:YLF and the absorption band of Ho3+:YAG, and the ability to produce a linearly polarized output.

RTP (RbTiOPO4) is an isomorph of KTP crystal. 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. The transmission range of RTP is 350 nm to 4500 nm.RTP crystal is widely used in laser Q-switching system with high frequency repetition, high power and narrow pulse width.

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.

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.

Thin film polarizers are based on interference within a dielectric optical thin-film coating on a thin glass substrate. They are made from composed materials which include a polarizing film, an inner protective film, a pressure-sensitive adhesive layer, and an outer protective film. Thin film polarizers are used for polarization separation, that's to say to change un-polarized beam into linear polarized beam.

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.

Tm:YAP crystal is one of the most important crystals for LD pumping 2μm laser. The anisotropic structure of Tm:YAP produces anisotropic emission cross section. Tm:YAP crystals with different orientations have different output wavelengths and operating forms for different functions. Compared with the physical and chemical properties of Tm:YAG, the 795nm pump absorption band of Tm:YAP matches the emission wavelength of commonly used high-power AlGaAs diodes better.

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.

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.

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.

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.
