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.

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

Yb:YAG's advantage is a wide pump band and an excellent emission cross section. It is ideal for diode pumping. The broad absorption band enables Yb:YAG to maintain uninterrupted pump efficiency across the typical thermal shift of diode output. High efficiency means a relatively small dimension Yb:YAG laser crystal will produce high power output. Based on the YAG host crystal, Yb:YAG can be quickly integrated into the laser design process.

Highly doped (50%) Erbium YAG is a well-known laser source for producing 2940nm emission, commonly used in medical (e.g. cosmetic skin resurfacing), and dental (e.g. oral surgery) applications due to the strong water and hydroxapatite absorption at this wavelength.Low doped (< 1%) Erbium YAG hase been studied as an efficient means to generate high power and high energy 1.6 micron 'eye-safe' laser emission thru 2 level resonant pumping schemes.

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.

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.

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.

BBO features good optical transparency from around 200nm to over 2µm, offers a high resistance to optical damage with power handling >3GW/cm2 for 1ns pulses at 1064nm. It is possible to use BBO Pockels cells at average power levels of hundreds of watts and power densities of several kW/cm2. In addition, BBO Q-switches have very low levels of piezo-electric resonances.

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.

Phase retardation plates, or waveplates, are polarizing optics used to manipulate the polarization state of the transmitting light without attenuating, deviating, or displacing the light. The working principle of the plate is to utilize the birefringence of certain materials which separates the incident light beam into two beams along two orthogonal optical axes within the medium. The phase retardation between the two beams of the incident light contributes to changes in the polarization state.

Polarizer is a kind of optical filter where the light transmission depends strongly on the polarization state. Normally, light with linear polarization in a certain direction is passed, and light polarized in an orthogonal direction is either absorbed or propagated to a different direction.For other directions of linear polarization with an angle θ against the“passing”direction, the transmission exhibits a cos2 θ dependence. That can be understood by considering that linear polarization state as a linear superposition of the "passing”and the“blocked”state.Most polarizers act

KTP Pockels are based on hydrothermal-grown high resistivity KTP crystals overcomes the common electrochromism damage of flux-grown KTP. Hydrothermal-grown KTP crystals have better optical homogeneity and higher damage threshold comparing to RTP crystals. This KTP crystal has large effective electro-optic coefficients and lower half-wave voltage. The Q-switch is built utilizing thermally compensated double crystal designs.

Wisoptic’s optical mirrors are available for use with light in the UV, VIS, and IR spectral regions. Optical mirrors with a metallic coating have high reflectivity over the widest spectral region, whereas mirrors with a broadband dielectric coating have a narrower spectral range of operation; the average reflectivity throughout the specified region is greater than 99%.

Optical Prisms are widely used to redirect light at a designated angle. They are ideal for ray deviation, or for adjusting the orientation of an image. An optical prism’s design determines how light interacts with it. When light enters an optical prism, it either reflects off an individual surface or several surfaces before exiting, or is refracted as it travels through the substrate.  WISOPTIC offers a wide range of optical prisms with various designs, substrates, or coatings.

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.

Nd: YLF (Nd:LiYF4) is a laser material that acts as an alternative to Nd:YAG. It is very suitable for working in mode-locked state to make pulse lasers at wavelength 1053nm, 1047nm, 1313nm, 1324nm and 1370 nm. Nd:YLF has very small thermal lens effect (much smaller than YAG crystal), wide fluorescent line, and can generate linear-polarized beam. The relatively small stimulated emission cross section of Nd:YLF makes it suitable for continuous work with low threshold.

A prism, in optics, is a piece of glass or other transparent object surrounded by two planes that intersect but are not parallel to each other. The most important parameters of a prism are the angle and material.  Prisms are capable to redirect light at a designated angle or adjust the orientation of an image. Therefore prism is useful for in certain spectroscopes, instruments for analyzing light and for determining the identity and structure of materials that emit or absorb light. An optical prism’s design determines how light interacts with it.

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.
